To stay or to go

I’ve been with my now husband for (this year) 6 years and we married this year February. I’m disappointed in myself for signing that paper, but i was 6 months pregnant and thought it was the right thing and because i loved him so much how bad could marriage be? The relationship wasn’t great but to me was worth it. Idk why but after being married i grow more annoyed or just don’t care. Looking back at it i know we both wasn’t ready 6 years and we still had some growing to do together and separate and the growing that needed to be done separate i didn’t care to be around for. Changes that could have been done years ago but no attempts made. Today we talked about taking a break. Realistically when i hear a break it’s done. Your gonna go do you and I’ll do me and why return to someone after doing dirt? I don’t want that in my mind thinking about who or what he’s done but he said it’s for us to really figure out if this is what we want for the rest of our lives. Why didn’t you think about this before signing the paper? Before i got fed up? Anytime before now ? I understand him wanting to be clear of his feelings and needing time to think but we have a baby (4months old now) and i never thought of raising our son in separate homes but the thought of me being unhappy seems to reason why we should be separate. He wants me to be pregnant tho, he keep saying he feels I’m pregnant but why would you want me to be? That doesn’t fix out problem. IDK WHAT TO FUCKING DO. Who would have though I’d be 25 and married with a baby. Never thought i could have kids and never thought anyone likes me enough for marriage for it to all end this way? Way to go to me
