I need relationship advice...

My boyfriend have been together for 2 years, but we were friends for about a year before we started dating. We have a cozy little apartment and 2 fur babies together. In January 2017, we got pregnant. We had no money, lived with room mates, and just knew that we wouldn’t be able to support ourselves or a baby in our own, so we decided to abort. We both agree that it was a mistake. But we were fine, we got on with our life together and promised that if it ever happened again, abortion was not an option. Fast forward to December 2017, our sex life took a plunge. He just wasn’t into it anymore. I thought maybe he was tired or just stressed and it would pass. We used to go at it like crazy. We had a ton of fun together and it was exciting! But now sex is almost non existent. I’ve had sex maybe 25 times in the past year. We’ve talked about it on the nights where we’ve had a little too much wine, and he says he thinks the abortion killed his libido. He said he thinks about it all the time. I feel bad because I never think about it. It’s been hard without sex, since I’m a 3 times a day kind of girl, and he used to be the same way. I know it’s not his fault, but he literally pushes me away when I ask, or try to turn him on. I don’t know what to do. I love him very much, but being rejected all the time is really wearing me out, and taking a hit in my self esteem. Any advice would be great.
