feeling depressed and worthless

Hi ladies for a long time I've been feeling depressed. 
When I was 17 I met a guy we got on and he took my virginity. I was stupid and did not use contraception and got pregnant and he forced me to abort and as the doctor was doing to procedure I started bleeding a lot and almost lost my life, when he was told this he said ' I honestly don't care' and blocked my number. 
I then met another guy and little did i know he had a girlfriend and we got into an altercation. Later on he apologised and we started talking again and he said he wants to see me but he doesn't want to take me out he just wants to chill ( yet on Snapchat I see him taking other females to 5 star restaurants) but he doesn't ever want to take me out which does make me feel like I'm not good enough for him and makes me so insecure about myself ( to the point I'm even considering plastic surgery). I don't know what to do really just thought I'd share what's in my heart.
