My ex boyfriend and I broke up a little less than a month ago. We're in high school, and we'd been dating for 6 1/2 months, if that helps. Things kind of got tense and less happy because we were both really busy, and didn't have time for each other and were pissy because of it. It was a semi-mutual breakup, and we agreed that we wanted to still be friends (we were good friends for about 2 years before we started dating). The thing that he doesn't know is that while our relationship was cooling off (about 2 weeks before we broke up), I started getting really close with this other guy, and I know that sort of pushed me to break up with my boyfriend too. We never really did anything, but it was clear that we really liked one another.
Now this guy and I just started dating a few days ago. My ex-boyfriend and I are totally fine: things are just like old times, and it's really not awkward at all. We've even talked candidly about our relationship since then, so I think we're going to be ok as friends. However, I'm still not sure when I should let him know about my new boyfriend. He knows that I knew the guy while we were dating, so will he assume that something was going on then too? I really don't want to ruin our friendship. Any advice?
I would be totally honest with him... mention that you're dating someone new and then be completely open with your previous boyfriend about nothing happening between the two of you during your relationship.
answer his questions and give him no reason to doubt what you have to say. be genuine, straightforward, and transparent. if you feel comfortable with it and you think he won't be mad, you might even talk with your old boyfriend about your current relationship with this new guy - where you see it going, how it is going, etc.
