So I had a fwb thing with a guy for nearly 3 yrs, everything was great and we had an amazing time together, he was 12 yrs younger than me and I had been married and had kids previously and I wasn't looking for that again, him being younger and not having had that it was always seen as we have fun until he meets someone to settle down with.
A year ago he meets someone and let's me know so that's it, I deleted his number and just got on with life as you do, thought about him sometimes but not often.
2 weeks ago I get a what's app message from a number I don't have stored on my phone, picture is generic and the message is just basically hi how's things, how are the kids etc so not knowing who it is I left it.
A few days ago another message saying ok just ignore me then!!!! So message back saying sorry don't have your number stored on my phone who is this?
It's my old fwb and then goes on to tell me how rude it is of me to have deleted his number!!!
I messaged back saying that as he was in a relationship therefore why would I keep his number? I'm not going to message someone who's with someone else
He's now pissed off that apparently I didn't care enough to keep his number but my thinking is we were just fwb and him being in a relationship (now ended) meant that I would not need his number anymore
