Search Results: getting over an ex relationship

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.
