Give me advice x

Okay so I’m going to go into a lot of detail and just pretend your listening to your best friend or something and give me some good advice lol tysm BE HONEST.

So basically I broke up with my boyfriend after a year nearly, we were really good he was very good to me like always there for me etc, but towards the end his friends (girls) started to get between us (and that seemed very suspicious because it was uncalled for) so I kicked off and I got snappy for like a week and he started getting snappy too and said there was no need and I shouldn’t let them get between us but like ovc I am becasue we were going strong until this unnecessary stuff happened I’m OBVIOUSLY going to be angry right?

So we carried on arguing he nearly finished me one night and I thought on to myself that maybe we should stop it here he doesn’t seem happy anymore and obvs all a girlfriend wants to do is make her bf happy but I couldn’t seem to do that anymore so I finished things and he didn’t seem too bothered. Now I’m texting him again nearly two weeks later and he’s being there for me and things always checking up for the past couple days and itsgreat but the thing is he said he doesn’t know what to do about us and he said his ‘head is all over’ like idk how to make this up to him Ik I shouldn’t have ended things so abruptly the way I did and like I need advice on how to sort this sh*t out. Do I bother trying? Or do I walk away? Does he care about me? WHAT DO YOU THINK PLEASE HELP x
