😥I feel depressed / Abortion

Okay I have kind of unsettling story that I will regret for the rest of my life 😩 but you know shit happens. I'm 18 years old and I've been with my bf for a year and a half and we always have had sex unprotected but I was on the pill 👌🏻but i missed it one day ☝️ and I found out I was pregnant 2 weeks ago. My boyfriend made me feel like it was my fault and that I had to get an abortion or he would leave me because he doesn't want kids 😭. That broke my heart because I'm so against abortions but for his happiness I went ahead with it at 6 weeks pregnant I took the pill abortion and it took 3 days for me to bleed out that baby. 😞 but now I find myself so depressed after. I start crying and he doesn't understand. I don't know what I should have done but no one supported me. I honestly want it back. I'm afraid I'll loose feelings for him after this but I do love him so much I just hope it was the right thing to do for the timing. What would you have done ??
