Boyfriend and I drifting apart?

My boyfriend and I have 2 kids together. A wonderful 3 year old boy and a four month old baby girl.

Lately it's been all about the kids. My boyfriend stays in the living room with our kids and I mostly stay in the bed in our room. I'm usually in bed because I work graveyard 4 days out of the week so I'm tired.

But my boyfriend and I feel as if we dont really like the same things. He watches anime and I hate anime.. I watch stupid girly movies and he hates my movies lol. Also, we can never watch things together because the kids are awake and we dont want out 3 year old watching adult television.

I'm starting to feel like our relationship is getting tough and I dont know what to do with my boyfriend anymore. We live alone but we're always on different sides of the apartment.

Any advice before it's too late?

Hes becoming convinced that we have NOTHING in common.

If that's true, is it a bad thing?

Should that be a deal breaker?
