I’ve been dating a guy for a few months now and things are progressing really well but an ex reached out to me yesterday saying he was going to be in my area and thought we could meet up. I told him that I was in a relationship and wanted to respect that and he was very respectful and wished me well. Now I wonder if I should let my boyfriend know? Would it just create a problem from nothing? Or would it be beneficial as a way to build trust?
