what do I do?

How do you know your done with a relationship. Me and my bf have been together for quite a while about 2 years well I just don’t feel the spark anymore I feel like he doesn’t wanna see me anymore bc he rather play his game. We have a baby on the way which I feel is the only reason why I feel like staying. He’s the best he really is he’s super nice caring all that but he lied to me not super bad just where I feel I can’t trust him about anything even tho it was a small lie. I feel like now the relationship is very boring we don’t go out and do fun things. We go out to eat maybe every Friday but that’s about it. I’m not sure. I cry of the thought of leaving him but also feel like I can’t trust him, he hasn’t cheated on me or anything close but it was a lie that meant something to me you know? So idk what to do, do I ask him to put the game away till we work our relationship out, ask him to do more things to speak up our relationship? Or do I leave? Because I’m not sure.
