I've recently met a guy (34 yo) through a friend of mine and we clicked and have been seeing each other for a few weeks. He treats me really well (drops things to come and look after me when I'm ill, replies to my messages in a timely manner, in short, he's there), things seem natural with him and we both seem to want the same things, but I have recently had a few doubts.
We were speaking very openly about values and past relationships, and he openly told me that he has once cheated on a partner after a difficult break-up when he was a lot younger, but that that is no longer something he does... He said he regrets it and that there were no excuses but, as someone who's been hurt before, I am understandably very hesitant to continue. My previous partner cheated on me and would go out on benders without contacting me for 24 hours afterwards; this new guy is also someone who goes out quite a lot, so I'm concerned that that would trigger me. I expressed my doubts very openly to him and he said that this is a period he's been through at the age of 20 but that he now knows that this is "not how a relationship works."
Should I cut things off or should I accept that we all go through wild phases and that this is in the past?
