Is our relationship gone?

So my boyfriend and I went to an event last night with some friends and everyone has their partners. Well everyone was happy like “this is my person” and just having a good time. My boyfriend doesnt do this and we have been together for 3 years just doesn’t seem confident in us or the relationship you can tell. We do have a baby and she’s a year old and some things have been tough but just doesn’t seem we support each other. I know social media isn’t everything but if we go to an event we have a handful of pictures of us he will leave me out of them. Sometimes I feel is okay but every event? And then you are on there but act like we aren’t together? Idk I try not to put to much thought but after last night we got a pic with a celebrity and he took one with us and he left me out and ones we took that night. Some days I feel our relationship is going down and it breaks my heart.
