Boyfriend/babies father doesn’t care

So this is my fourth pregnancy with my boyfriend.

Our first two were happy oops.

Our third wasnt planned but wasn’t prevented but I had a miscarriage.

Our fourth was planned.

Well, I am almost 21 weeks with our fourth and my boyfriend refuses to feel the baby kick, most of the time he acts like I’m not even pregnant.

I don’t understand why.

I feel alone in this pregnancy...
