Am i over reacting?

My boyfriend and I have rarely talked all week and if we say something we end up disagreeing about everything. So the issue here is that i caught him texting to other women on Facebook it wasn't just one there was multiple girls and the conversation were all sexual so i confronted him about it and we got in a really bad argument which I think is stupid because he still has the nerve to get mad at me for checking his Facebook. We came to a conclusion that we were going to get passed it and "MOVE ON" I have to be real its really not that easy to forgive and forget bc it hasn't been the first time i catch with some shit. So its been about 2 weeks prior from the day we had our argument and at that time we both agree he was going to delete his Facebook and hasn't done that now this week i told him what happened to what we agreed on his response was that he doesn't know how to delete it lol Hahahaha and that he already tried but he said it usually takes a few weeks to deactivate 🤔 im like wait a minute why does yours take a week and mine took less then 2 minutes to deactivate.

My conditions were for him to deactivate his Facebook in order to try to work on things i feel like he really doesn't care bc I've ask if you can't deactivate it I'll do it for you he SAID NO bc he doesn't touch my phone why do i have to go on his.Plus he said in what way does It affect me if hes not going on Facebook anymore. HUH? I did my part for 2 weeks and not say anything and not bring up shit to pick up a fight I mean all of this just seems like everything we talked about 2 weeks ago was for shit bc now hes back to getting all defensive and since i told him not to speak to me until he does what we agreed on he hasn't really said anything to me either this week. He said he doesn't go on Facebook anymore im not stupid. I feel like with all we've been threw i should be able to demand and put my foot down with what i want our relationship to be.

Im already at that point where im not happy in the relationship and i ask myself is it worth it? All these years for nothing and for him to say im wrong bc we were good for the pass 2 weeks. I mean we are really not getting any younger i got 4 kids all i want is for us to get along and enjoy the kids and time as family. I've told him all that shit that your doing is not going to get you anywhere why give time to girls or people that haven't done shit for you at the end of the day the only people that matter should be our kids and me.
