Hey everyone, so to give a little background to this. Me and my boyfriend have been together a few years, we have a 1 year old. I've caught him messaging a girl on Facebook a while ago but because of our son I thought I was doing the right thing and forgave him and moved on from it. (He deleted his social media) but recently I've just had a feeling he was upto no good again and plus he told me his father had give his number to his gf's daughter to text him and give my boyfriend her number but he said he just blocked her number after she text him, I said ok but wasn't very convinced so I looked through his phone and seen he had been messaging her and arranging to phone her and saved her number with a man's name. I went to his Whatsapp and a picture of the girl appeared, so he was texting her. I don't know what to do. Do I forgive him AGAIN? I'm just so hurt by this.
