Been with my boyfriend just over a year, it has been complicated and we do argue most of the time when he wasn't with me and working. But for a month we have finally stopped all that and became settled. But a couple of days of ago I've found out that the last time we argued the other month ) he had gone to another woman's house to give her a fag and chat I have asked this woman what happened and she said he only stayed 10 mins and said he needed to go, he said he realised it was a mistake and left. Nothing happened. But I can't get it out of my head. What if he does it again. And is he really going straight back to his after work etc when he does. All his time off he spends with me and a couple of times when he works he stays over basically nearly moved in. Should I just let it go seen as we were constant arguing and got better? My mind is in constant overdrive.
