Boyfriends “slip of tongue”

I was talking to my boyfriend and asking which guys in his friends group were with which girls. He said there’s only 1 single guy in the group and “lucky thing gets to sleep around”. I thought he was joking and said “lucky?!” He said, oh Slip of tongue.. i meant he gets lucky not that he’s lucky to sleep around.

I asked him at that point does he still want to be with me, because lately things are different. He doesn’t hold my hand, won’t take photos with me, hardly texts me back, never comes over to see me. And he said “I do want to be with you, it’s just we don’t see each other much coz we’re both busy”.

That was pretty much the end of the convo. I still am not convinced he wants to be with me but I don’t know what to do. I love him so much and it hurts me thinking about if we’ll break up. We’ve been together over a year and the honeymoon phase keeps going for me, but for him, it seems to have ended pretty quickly.

I just feel like he doesn’t want me, but I don’t want to keep asking and seeming insecure.

Help please?? Any advice x
