After all this time, I suggest you move on. If he doesn't want his friends or Family to know about you, he doesn't value you enough. You deserve someone who is proud to be with you and let everyone know. That said, he likely is trying to schmooze another person and will leave you if he makes progress there. It appears you are his FWB, not girlfriend/lover.

You're one of several side pieces, each kept apart from each other. Or if you are exclusive, you're not the one, probably never will be, and he's keeping his options open. Either way, if you're not okay with this arrangement, dump him.

He’s playing you. In a relationship for over a year and he doesn’t post you on social media? Girl run don’t walk. He’s keeping you under wraps because he’s protecting someone else’s feelings or he’s trying to keep his options open. This guy is obviously very active on social media about his life, but not his relationship of a year?! Massive red flag - he wants to appear single. RUN.

Dump him now.

🚩🚩🚩

He doesn't love you, you're just his bed warmer until something better comes along. Walk away and find someone who finds both pride and joy in your relationship.
