Old Aries Friend

Not really had much call to be on the Aries board, but an old Aries friend of mine has got back in contact over the past few months and I was hoping you guys could give me some advice on how to handle him!

Some background: I met him 6 years ago, he was a good friend of my Pisces ex so the 3 of us plus my ex's bro (Scorpio) would hang out together nearly every day. I was closest to the Aries as my ex and his bro were pretty close so the two of us would chat together. Nothing sexual or anything, I never thought of him that way. Then I split with my ex because of his violence towards me after 4 years, and I made a total split from all of them, which was hard, but I felt it was necassary for me to heal and move on, which I have done. I saw this Aries last year and I got so emotional seeing him I was crying, which felt weird; we had a really long cuddle and he told me how much he had missed me etc. Over the past couple of months we've been emailing each other, just about what we've been doing and talking about old times. The thing is, his emails have slightly changed in tone, like he's started talking about how he liked me when I was with my ex and stuff like that. I'm currently in a relationship with another Pisces (I didn't learn the first time lol) and I don't want to lose contact again with the Aries as he was a good friend to me(he would stick up for me to my ex, which got him into physical altercations at times).

Basically, how best do I let him know that although I love him dearly as a friend, I'm not interested in anything more. I've been confiding in him about the problems I'm having with my Pisces and I feel he may think that I'm trying to show the way is open for him, which it isn't, I have enough hassle with the Pisces at the moment without adding extra on top!

I feel really stupid about this.

Thanks GF, I don't want to change things with him, but I kind of realise now that it perhaps wasn't the best idea to confide in him, although he does the same to me about his pisces gf. We still have mutual friends and I might be seeing him at the wkend, so I hope I don't get all emotional again, cos he seems to bring it out in me for some reason.

I need to sort things with Pisces that's for sure. Everything wrong with us is my fault apparently and every time I try and defend myself I'm selfish according to him, but he can defend himself to the hilt and it's ok. It's driving me mad!!!! Maybe that's why the Aries is looking more agreeable, he's always accepeted me, warts and all.

Sorry, just needed to rant!!
