Got it — you’re 29 and he’s 30 and you broke up after two years because he lost interest in the relationship and it didn’t seem to have any forward motion. All that makes sense. That he disconnected you from his social media also makes a lot of sense given the break up. Lots of people do this to help themselves move on, and I think he was right to do this. Seeing an ex on social media can be a painful reminder that you’re not together and that one or both of you are moving on, or are dating again. During a break up there’s often a need for boundaries and space to help one and/or both of you to move on. That you’re upset about it is just because it’s like the scab of the breakup being picked at again, now that you see another place in the world where the two of you are not together any more — even as social media buddies. It’s normal and the pain will help you move on.
You’re at an age where it sounds like you’re looking for marriage, and it’s good to have a goal that you’re clear on. But make sure that when you start dating again, that you focus on that goal. Lots of times people pull the wool over their own eyes about problems in the relationship, hoping they can will changes. If you have deal breakers between you, move on. And if only one of you wants to be in the relationship and work on it, as painful as that is, it’s a big clue that a break up is coming.
