Pregnant & need help

So ive been with my boyfriend for 2 year, going on 3 years on Jan 23. We live togther, & im currently pregnant with my first child & his second. Things have been rocky between us, we cant seem to agree on anything, we bumps heads alot. Everytime we have a serious conversation we always argue. I tell him i want us to spend quality time, since the baby is almost here & once she is here we wont be able to do nothing. One because i know my attention will be on her since its my first child & two because i don't think i will trust just anyone with my baby. I told him before you dont give me time of day, im pregnant with your child & you cant even try to be supportive of my feelings i just want us to enjoy each other before its plus one. & he just says why were always arguing. Your always negative & so on, & so on, which i think is just bullshit

It's sad to say but part of me always knew i would be a single mother. Long story short he hasn't seen his son going on a year, his excuse is he doesnt want to deal with baby mama since she is drama. I feel like he is just going to leave me alone with a kid like he did to her. I mean if that was to happen, fuck it i always knew i was going to be a single mom. But deep inside it hurts me alot because i was raised by my dad( my dad is real mvp rasied two kids without the mother, & never gave up on his kids even in hard times) & my mom would come & go out of my life. I want my daughter to have both parents. But i cant force him to man up.

Every time i think of my future with my daugther i only picture her & i alone without him. I picture a better future for us............... But deep inside it hurts because i really love him & i feel like if i leave he is just going to find another girl & get her pregnant & do the same shit. He is my first boyfriend. My family isnt a fan of him, they all say i can do better & i deserve better. But i know he is a good guy deep in there, but then part of me knows i wont get my old Edgar back. 💔😭Idk if im in love with the though of him or the words he told me before. But even thinking of him & i breaking up, breaks my heart to the point tears are coming out as i write this because really love this man.

Is it just me?! But if a man love his women like he says he does, he would be more affectionate when she is pregnant with his child or lovable & understanding? Ladies how was your man during your pregnancy? Please, Ask your man also since there guys they should also give good advice right or wrong? I just need help or word of advice.

Im 30 weeks pregnant & need to know what i should do before my baby girl is here & we keep this relationship going & he walks away & breaks my daughter heart. Like he is doing with his son. I just want to protect her the best i can. I was that kid thinking my mom cared & she was coming for me & mom never showed up only when she wanted to. I dont want a part time parent in my baby girls life.
