In the immortal words of George Michael: You gotta have faith. Or at least trust.
I'm just going to take a wild shot in the dark here and assume that due to bad events in your past, you've got a few trust issues. That's going to complicate any relationship, and to a point, yes, you do need to trust him. Dredging up the fact that he danced with somebody else once, for example, is both petty and unfair. You need to let that go.
On the other hand, this is a two-way street. He needs to be able to demonstrate that he's worthy of your trust. Everybody needs space and time alone, but he needs to respect that's difficult for you, and, if he's doing something on his own, check in with you occasionally. That's not asking too much, and it's the least he can do.
It's especially important to not throw things in his face and give him space bc he's not going to want to tell u anything that might upset u. it leads to lying and just no communication whatsoever. Which one would you take? Sucking it up and learning to trust him or him not telling you anything and you feeling even more paranoid.
Space is ok to have. It can help you guys enjoy your time together even more than you already do. It is not ok to use dirty fighting techniques like bringing up everything he ever did wrong when you have an argument. How is he supposed to combat that? It's childish and bad form. Next time you have an argument, stick to the topic, resolve it, and then move on. No more bringing it up and throwing it in his face!
Start making your own plans, rather than hanging around waiting to see when he's free. Keep your social life busy, it will be good for you. When someone says they need space, thats cool - of course you're going to feel a little rejected, naturally - but keep yourself busy and you can overcome that feeling. I find SOME guys hate it when you are always available, but as soon as you start planning lots of fun stuff with your friends they are soon back at your side wanting all of your attention.
Stop bringing up his past! Like seriously, get over it or let him go. He's probably right, you do need to change because his past aint going anywhere. Look at this way, realistically, what good is it doing to you or him by bringing up his past? You're in the middle of the fight and you throw something out there about him dancing with someone else.. do you honestly think a low blow from the side like that is going to reconcile the current situation. Of course not, but what it looks like you are trying to do is pressure him in to feeling guilty, so that you immediately get the upperhand in the argument and he's probably tired of it! My boyfriend used to this to me - Each time he brought up something about my past, it not only infuriated me beyond belief but I lost a little bit of respect for him. It certainly didn't make me feel any closer to him, (And I didn't even ever give him any reason to mistrust me in the first place! He just didn't like the fact that I had a past!!!) If anything it drove a wedge between us. Maybe this is why he needs space, because you are on top of him with your trust issues. If he did something for you to mistrust him, then sure of course you are going to have difficulties trusting him but remember YOU made the decision not to end things with this guy - hence indicating that you made the decision to work on this trust issue and get over whatever he did. You can't make someone feel continously bad for a mistake they made in the past. It will grow old and sour. And he will resent you, eventually.
It is absolutely true. The only thing he's ever really done is dance with a girl real quick and igot really upset bc i think of it in my case when i dance w a guy i obviously am attracted to them and i get flustered bc when he goes out w his guys he gets so drunk. either way trust issues come from him cheating on his ex w me and im not innocent either bc i did the same thing and thats how we ended together kind of messed up but it worke dout all right now its hard because i get scared the same thing is going to happen which is when i dont give space and i just want to go everywhere and i think what if his ex is there and he gets drunk and flirts w her and what not and all sorts of terrible thoughts so yeah i guess i'm a little damaged by all the cheating i've done
