Would you trust someone after they had a rebound then came back?

Was really good with this guy, thought I’d found ‘the one’, then he started struggling, said he had no time for me and split with me after 6 months.

I was devastated, he got with another girl 2 weeks after splitting with me, 4 weeks after got back in touch with me. I didn’t make it easy to talk but he revealed he still had feelings. Was really up and down - would say positive things but didn’t want to do anything about it.

Then had a turning point when I saw him on a night out and gave him a piece of my mind of everything that had built up. Then he turned sensible and asked for me back, said he would do anything, has always loved me, and take it as slow as I wanted. Said the girl was just his way of dealing with it and wish he hadn’t done it.

However he told me it was a one night thing, but in truth I know it was more than that, he did spend a bit of time with her. We’ve been back together a month and he’s been great but I can’t get past it. Do you trust someone like this again?
