We've known each other since we were practically kids. There was a brief engagement in our early 20s that I called off but we agreed to stay friends which worked well as we have alot of mutual friends between us. One of my closest friends is also one of his. No problems.
I'm settled down with somebody now and have children but we'd catch up on social media when he'd get in touch which he often did.
He has recently got engaged which I thought was wonderful, I sent my congratulations and said I was genuinely pleased for him (and meant it!)
He thanked me, asked how I was, we exchanged pleasantries and that was that. There was no negative interaction whatsoever.
Now I've just realised tonight that he has deleted me from social media as he came up in my suggested friends.
I've no plans to contact him and ask what that's about but I am a bit baffled and disheartened because I thought he saw me as a friend, I did him.
Am I a bad memory? Is it disrespectful to a new partner to keep exes as friends to some people? (DH doesn't think so)
