Break up or not to break up

I need advice on if I should break up with my boyfriend of six months.. so lately we haven’t really been talking but he’s a supervisor at work so I understand and I don’t expect him to stop What he’s doing just talk to me. But we haven’t hung out in the last three weeks except once and It was to sleep over. Well three weeks ago I wanted to take him out to a winery for dinner to show how much I appreciate him I booked the reservation and everything but once he found out where we were going he said he refused to go because it was too fancy for him . I said okay and and we went to a Chinese buffet. That was the last time we really talked or saw each other because after that we planned a movie night and he cancelled and said the guys called for drinks. Someone asked why he was with me and he said because I wasn’t crazy. He’s single on Facebook And mine doesn’t say anything on my Facebook because like to keep my personal life offline and mine doesn’t say single. I told him today if he keeps neglecting me my Facebook status is going to say single and he just laughed . I asked him if he wanted to hangout tonight after work since it’s his day off. I wanted to talk with him about how not talking or seeing him affects me and his relationship and he never wrote me back but he commented on other peoples posts. Is having that conversation even worth the trouble or should I just move on? I say this because I told him a few times I think we have issues in our relationship and he just says alright.

*im starting to feel like a part time girlfriend.

*I asked him to hangout so I can break the news to him and he said tomorrow would be better, great so he can’t even make it to the breakup session
