Anyone been through this...?

Ariana • Hi I'm ariana! Pregnant with my first❤🍼
My boyfriend and I have been together 2 years and 3 months now(he's 19 and I'm 17 & 19 weeks pregnant with our first) and we had a really big fight today because of the fact that he said "you're still my girlfriend but I don't know if I want to be in a relationship anymore... and I don't want to treat you as my girlfriend because then that will mean that I've made my decision to be with you. I need to think about it"... but he's been thinking about it for over 2 months now... am I wrong for demanding answers? what does that mean? I have no idea how to handle this... we don't live together, so should I text him? Should I wait for him? I've tried reaching out to him multiple times and gotten treated as if I'm a piece a gum on the bottom of his shoe... should i give up... I'm so hurt... and I hate that I'm putting my unborn baby through all this hurt, tears, and pain... any advice?
