Should I tell him?

Me and my Bf have been together for 4 years. I love him so much and our families loves us together. But the last year was rocky because I wanted to talk about marriage next steps etc after 4 years...and he kept using the general excuse “we are not financially ready” ummm we make well over 6 Figures together. Anyway after a year of discussing marriage I gave up.

I told him he should follow his dreams and I’ll follow mine. We both got our own places but we kept hooking up here and there.

That whole 4 years I only had sex with him. Neither of us have ever been with anyone else during our relationship.

Anyway...On one of breaks he asked if I could pick him up from the airport and I did and ended up staying at his place for like a week and we had lots of sex, unprotected sex cause before this this was my bf of 4 years.

I got preggo. (Unknowingly)

At the end of that week he’s calling me babe, acting like we are together and I ask the question of what’s next for us and again, he just wants to continue what we’ve been doing. Nothing more than gf/bf.

I pack my shit and finally I say I’m done with him forever and I’m moving on. I even told him and we both AGREED.

About 4 weeks later I meet a new guy we date maybe 4 times and we have sex 1 time. And this man was beautiful, rich, was looking for a wife, I thought my dreams came true.

But Boom it’s also 4 weeks after having sex with my ex and I miss my period and find out I’m preggo. JUST MY LUCK.

I didn’t realize I was ovulating around the time I was with my ex/bf, but based on my calendar I was.

I decided to cut ties with the new guy, because now my ex/bf is soooo excited to be a father 🙄, wants us to get a house and move in together. Should I tell him what happened or no? I’m 12 weeks preggo now and I love this baby so much already and I love my bf. It’s been 4 years. But like what’s next?!! Ughhhh I just want him to do what’s right for our family.

Update: I found out I was preggo the same week I had sex with the other guy. I was already 4 weeks based on my U/S dating scan. (And I wasn’t ovulating around that time)

But It’s on my conscience for some reason idk why. Maybe because he was the only guy I had been with for 4 years.

Anyway, I’m keeping my mouth shut!! Thanks ladies!!
