we have been together for 8 months, my partner has been single for the past 10 years and insisted he was ready to be in a committed relationship. I found out he was sending inappropriate messages to a female he was seeing a couple of years ago - they remained friends as they work together however the messages were disrespectful to me.
I’ve confronted him, though he apologised he hasn’t shown much remorse or done much to suggest change. He said they remained inappropriate as that’s what he was used to with them and he’s been single for so long it “slipped” his mind but he was sorry. I also confronted the woman who said nothing physical happened, she is in a relationship and that she thinks he really cares about me and just isn’t used to being with someone. All terrible excuses, I’m unsure what to do with it. He has been great otherwise, I’d never think he would do anything like it, if anything he was more keen on me than I was on him! But naturally I’m hurt.
do I forgive and move on or do I end it?
