Dealing with disappointments

I'm rational and sometimes I don't know if what I feel is normal when it comes to relationships. I'm also very patient, understanding and naive, and sometimes people just abuse my good side.

With that said, lately, my man and I have been fighting a lot mostly because of disappointments.
Few examples:
-He will invite me over his place to hangout and spend time with him and do something he knows I like. Then, after 30 minutes he will find what we do boring and will wanna do something else something he's into and I'm not. We will fight, because I drove an hour to go to his house and he lets me down. Usually he realizes he's in the wrong and will say he's sorry and we will go back to what we were doing first. But each time, we argue and fight.
-He will plan things with me. Like dinner or a movie, and in the day text me to tell me plans won't work because he will hangout with someone else.
-There's a girl he works with. She's into him. And he made it clear with her he's not available. But still text her all the time.
-He flirts with girls on social media. I told him I'm fine with it as long as he doesn't cross a line. (I mean, to me, him flirting with a girl on twitter who lives states away is not a problem to me) but he did cross a line when they started texting and flirting.
-He will invite me to spend the night at his house for us to cuddle and watch TV and make love, but then he will start playing video games and I will end up falling asleep while he's on his xbox.
-He will forget about our dates. Sometimes I planned something for let's say, monday night. And in the day I'll text him with a "Can't wait for tonight!" and he'll reply with "Oh shit I forgot! I can't, I have to go to Mike's I promise I'd help him with his bike"
And so we will fight and argue. Because once or twice is ok, but when it's often it's too much.

I just don't know what to do. I don't wanna break up with him. I tried talking to him, he understands but he will keep doing those things anyways.

Are those things normal in a relationship?

There's not a whole lot of respect or love coming from this man...are you happy to just receive his crumbs because the chances of it getting any better are very slim!!

Your not a priority and doesn't sound like you ever will be and the way he is treating you has red flags all over it!!

Your choice though, you obviously don't feel you deserve better!

Mmmm yeah he sounds suspect. Perhaps he's flaking on these dates with you b/c you're not the only woman in his life.

I get it. Some men are just downright forgetful & half of that is b/c it's in their DNA & the other half is b/c it takes awhile for them to remember that something is important to you if that specific thing isn't at all important to them.

BUT if a man is truly invested in you & wants to make you happy, he'll remember, if anything just to make sure he doesn't have to hear you bi***ch & moan about it.

The fact that you've voiced your concern 100 times & yet nothing has changed, bothers me & leads me to ask you to reconsider that his lack of making you a priority might be from you literally NOT being a priority as opposed to the excuse being that he suddenly has memory loss when it comes to you

Personally, I think this guy being so flaky is reflective of how he feels about you/the relationship. It'd be different if he didn't know it bothered you, but he does & he keeps doing it. And the fact that there's even an argument after he's the 1 in the wrong tells me that he clearly doesn't plan on stopping.

When you know you're in the wrong & wanna fix something, you don't keep "right-fighting" with someone. The only time someone argues with you when you think they've done something wrong is when they secretly don't think they're in the wrong
