Need some advice on how to continue.

I posted the other day about understanding my cancer girlfriend/ex girlfriend as I am a Pisces male. Unfortunately I don't know our rising or moon signs etc, just sun.

Regardless, she is definition of cancer. She's incredibly caring and loving and seemingly loyal, but also very easily withdraws and pushes me away when she feels its justified on her end. This happened in the beginning of our 6 month relationship where she went "into hiding" for about 2 days and suggested us not being right for each other. I don't actually remember the real reason now. This basically led me into a lot of insecurity and a lot of overthinking (I'm also a typical pisces) and would think of every scenario that could happen that would break us up and I would talk to her about these. These were the times when she'd withdraw and hide for a day or two and we'd kiss and make up then go back to normal.

Go back about three weeks and I was at my worst. Almost daily I'd mention something that would snowball into an argument about how I think she's going to leave me because she doesn't see her friends as much, or she'll find someone better, etc. Mainly from the fear of her constantly withdrawing and pushing me away but more so my past and all those failed relationships where I was basically blindsided (almost all aquarius females). This really took a toll on her but being she wasn't so open about it and stuck by my side and supported me, I didn't notice how much it hurt. She basically blew up, shut down and ended it. I chased her for a week and she wouldn't budge. Finally on Valentine's Day she asked to talk and we did face to face, hugged, kissed and told each other we loved each other. I talked about everything I did wrong; that I was insensitive to her feelings and everything I could possibly say. She stayed over and the next morning she woke up normal but as the day went on she got insecure and said she scared and was hinting that it was a mistake to get back together. That night she came over to grab her purse she forgot, apologized for being crazy and stayed over like normal.

That entire week had no problems. This last weekend was my birthday and I was with her Friday-Monday morning and everything wasn't exactly the same but definitely good like a work in progress. But later Monday she got insecure and scared again then said she isn't sure if she can trust me or if it'll ever be the same. I did nothing to provoke these feelings, she just came out with them on her own and is now in the process of telling us we need to go our separate ways.

I don't know what to do because letting her go will be the most painful thing I've experienced. I turned 31 on Sunday and this is the first time I've ever actually felt in love; felt complete. She used to say all these things about me but I understand she's hurt, but hurt enough to let me go for good without really giving me a chance to prove otherwise? It's been a week and there's no way we can go back to how it was that fast but she doesn't realize it. I just wish I knew how to handle her or make this work out better and for her to trust/believe me. Sorry this is so long BTW......

What do you mean by 'there's no way we can go back to how it was that fast'? How fast do you want it to happen?

It's a long process, it takes time and that's what you have to give her. Time to figure it out by herself. If she wants to be with you, she'll be back. If she doesn't - then you don't need her. Imagine if you got back with her right now when she's full of doubts. Your overthinking+her doubts = the answer is quite clear, right?

Besides, you also need some time to let the picture clear. It will be hard, I'm talking from experience, but you'll see everything in a different light yourself included.

She's not getting "insecure". You're the one being insecure and pushing her away. She's with you. What more do you need? Everyone has arguments. It's life and it happens. Just because you have an argument dosent mean she's gonna leave you.

My advice would be to simply RELAX

Thanks guys/gals for the replies. Thing is my focal point and I expressed this more than enough was that nothing was going to change or be better that soon. I feel like she expected herself to feel better about it sooner but only gave me a week and since she didn't she thought it best to bail again. So we are not together as of now.

Once again, she's back but this time it seems much better than it did last week. Last week we had made up but I still felt a weird "negative air" floating around us that I couldn't really explain or pinpoint the cause or reason. Obviously this weekend proved that because of how she ended up acting but now it seems we cleared out all negativity. She apologized for acting crazy and knows that since she's never been in love like she is with me before, she thinks it's just easier to run away with fear rather than face it and move forward. She chose to move forward and so far it seems like we got rid of a lot of that fear and realized I supported her this entire time and have been nothing but patient. Hopefully it stays this way.

It takes us a long time to fully open up..but if we can trust you, you have us for life!
