7-year relationship ends with rebound-abortion

hi! so I was dating my boyfriend for seven years when we broke up. We both rebounded and dated other people for about two years, but in those two years i dated only one person and I ended up pregnant. When i found out I was pregnant I went to a local planned parenthood and they weren’t able to give me the pill because there was a heartbeat. My state has the heartbeat law so the only other option I had was to drive out of state. I woke up at 4 AM one morning and drove five hours by myself out of state to get the pill. Not that we need an explanation, but we both just weren’t ready and we weren’t in a stable place to be trying to bring a child into the world. I went to the Planned Parenthood, got the pill, and drove back home without anybody knowing what even happened. spent the whole day in bed and agony and then moved on the next day like nothing ever happened. It’s almost been two years now since that has happened and I still haven’t figured out how I could wrap my head around, or accept, that I did that. and to make matters worse me and my boyfriend of 7 years got back together recently & I feel like it’s something I need to tell him. at the same time, i’m wondering do I really need to tell him? he’s always talked about wanting kids together and we’ve never been that ‘safe’, I used to think we were just lucky but after I started messing with somebody else and ended up pregnant after just a few months, I realized maybe it wasn’t just our luck. I know he’d be devastated if I told him that I did this while we were broken up, and I think it would make him feel even worse because we’ve been together for almost 7 years now and never even had a pregnancy scare. it’s one of those things where, yeah, it’s not technically their business and they don’t have to know, but also it’s something that I feel i need to admit. Especially because he’s been begging me to start a family since we’ve got back together. I 100% know that it was the right thing to do, I just don’t know how to go about talking to him about it or if I even should. I’ve never talked to anybody about it, this is the first time I’ve even spoke about it to anybody other than my ex-boyfriend. I guess my question for everybody is how can I live with myself? there’s no way I can tell him that this happened, not only would he be completely devastated, but he’d probably be extremely mad at me for getting an abortion because he’s against stuff like that in the first place. I’m scared it will ruin everything but at the same time I feel like that’s a really big thing to hide from your significant other. Is it wrong of me to not want to tell him ever——what if we get married and have kids together one day and I still never have told him that I had an abortion? at that point it’ll be too late. What do you all think i should do? Leave it be or admit it to him?

TL;DR: I accidentally got pregnant on a two year break from my seven year relationship. I had an abortion, but my seven year relationship and I are back together now and I don’t know if I should tell him. Need opinions!
