17 & pregnant with baby #2

So I got pregnant at 15, had my daughter when I was 16 & now I'm 17 expecting my second baby... I feel so alone though as my kids dad is not there for me, he rather party than raise his baby that misses him so much & yet I'm here looking stupid for taking him back when I knew he wasn't going to change... I'm 5 weeks & 4 days pregnant.. Found out about 2 weeks ago.. Texted him told him, never even got a reply back.. This hurts. I'm just looking for support. Anybody have baby daddy problems? Or where your still in love but can't let them go.. But you gotta..
