I am so broken

Last night me and my bf had a conversation about why we are together. Long story short, we havent been in love w eachother for a long time but we love each other as people, and parents to our kids and he's too the point like why are we still holding on. Like how long are we going to keep doing this to ourselves? Theres no love, affection or sexual activity going on. I get it but i am so hurt. On top of that Im pregnant w my 2nd daughter by him. ( i have a son from previous, we have a 2 1/2 yr old together and then this one due in Nov) lm almost 7 months and i feel like why didn't we think about this before having another baby! I feel so broken hearted and i find myself deeply crying by myself and alone.

I can feel that hes done. Hes been showing me without even really knowing it. We both need to work on it but we just dont. We've been going through this for so long already

We know what we need to do to make us last and neither of us puts in the effort.

We just got into a stupid argument, super petty and now Im bawling my eyes out ALONE.

This is what I sent him. Someone tell me life will get easier. That everything will be ok if we don't workout?!?! I need some strength, guidance, something. I feel like i have nothing right now and im losing more and more everyday.

I don't work right now, but will after the baby is born.
