Should I have an abortion or no opinions

So I accepted the fact of having a second baby which wasn't going to be so bad if I had help.

Well I found out my boyfriend had been cheating and I can't even stomach to look at him it's over. (We've been on an off but together for years)

I'm 15 weeks, everyone knows I am pregnant, but I seriously want an abortion I don't want to do adoption because I don't believe I will go through with it.

I struggled with this decision early pregnancy and decided against it and I am now feeling it is a mistake.

I know this is a later term abortion so it's a controversial subject a response I got from many other people was "shouldn't of got pregnant if you didn't want a baby" or "why weren't you on birth control. (I am allergic to ever birth control on the market except the copper IUD) and I have a latex allergy and I was in a 4 year relationship and pull out had worked since the beginning (I know it's not 100% effective)

I just want to know should I really have to wreck my life and go through with this, and be shamed because of a mistake. I want to find love, I don't want to be stuck in a house looking at a constant reminder of someone who did awful things

I know if I had this baby I would not go through with adoption, and I would love it but still that's not the life I want to live.

I'm honestly just looking for advice, not rude comments on how I'm a piece of shit selfish whore

The clinic will do it up to 24 weeks

I posted this in another group and they told me about this one I am open to hearing both sides yes or no. But I don't want to hear anyone tell me not to because I'm "killing my baby" hearing abortion stories may also be helpful please just comment what you think would be most helpful thank you
