Im curious by nature & I just FB searched my ex from 16 almost 17 years ago. My first/ his first etc etc.
We broke up after 2 years when I met my now DH. I kinda feel bad I guess for how badly the ex took the break up. I never cheated on him, he just took it really bad. Anyway I have looked from time to time & he never came up, but I just found him on FB. He looks happy, appears to have 3 kids. My DH would probably be weird if I contacted the ex & just said that I was happy to see he move on in life & is happy. But I kinda want too.

Leave it alone? or not a big deal if I was too do that?
