Search Results: chance of getting back together

I was with him for only a few months but cared deeply for him. He's already a dad, and has a six year old daughter whom he has joint custody of. He is a phenomenal dad and I know he wants to have more kids in the future, but not quite at this moment. Stupidly, we weren't always the most careful with birth control, and then I went on the pill only about a month ago, mid-cycle. We broke up three days ago. I found out that I was miscarrying a baby yesterday. The doctor estimated it at only 5 weeks, and I didn't know I was pregnant due to cycle changes with the pill. Regardless, it's still a terrible emotional and physical pain, especially at this already fragile time.

So... should I tell him? A part of me feels like he has the right to know, another part of me feels like I should just let it be.

To be clear, I would not be telling him this information in hopes of getting back together right now. More of just an FYI. There is a small chance that we could get back together in the future, as our relationship ended over being in very different places in our lives, and both of us being super busy and not having a ton of time and energy to put into a relationship, but we both still have pretty intense feelings for each other. It just doesn't work right now.

Incase you don't get my question. Let's say you and your girlfriend were on a break, then were on the road to getting back together when suddenly you start fighting and end it for good (your girlfriend tells you I'm done with you get out etc, tells you that you're no longer together). The next day you find yourself super drunk and hooking up with an old hookup. After this, you realize you want your girlfriend back and that you should've just worked out your problems. Do you tell her what you did while you were broken up? Or not say a word in the hopes that you have a chance of getting back together. Also if you're not young, put yourself in a 19 year olds place (aka not so mature). I'm asking because my boyfriend lied to me about this for an entire year. Then he finally admitted it to me. I understand we weren't together and immature and it's been so long and he's a changed guy, but I'm having a hard time accepting that he lied to me ( I did ask him multiple times before and he always said nothing happened). I know he was scared and knew he made a mistake and changed after that incident for the better and has never had contact with that girl again but that's not important to me, just the lying.
