If you have texted then you have made the first move. Although you are inpatient you have to give him some times to respond . You have a right to be angry although you handled this very badly. If he really cares this one fight won't end everything. You before this is worked out have to find out if the boundaries of the relationship has been violated by his meeting up with this girl. Don't be overzealous to keep relationship that you accept things that are against what you want to tolerate. Connect with him but don't be too accepting. Text him once more to see if he is ready to talk.
If this has been helpful press accept
I'm just scared that he doesn't love me anymore and I screwed up bad. We both said things but he got really angry at me. We were engaged and my birthday is XXXXX 3 days. I'm just afraid he doesn't care enough and will never talk to me again. I don't want to be a pest and keep texting him because he probably wants his space.
I know he also screwed up and shouldn't have danced with that girl. He says it is just dancing but I have trust issues from my upbringing. He got mad at me when I got angry with him for dancing and never allowed me to be upset about it. Which made me even more angry. I'm not sure what to do. If I should start moving on or keep missing him and being heartbroken.
