Really don’t know what to do about the situation

Me and my baby daddy have had our problems in the past but we’ve moved past that and we’re friends, we do anything we can to help each other.

Well along the way I became best friends with his at the time girlfriend (they are currently broken up BUT she still tells everybody they’re together.)

Okay well she’s started flirting with a guy she used to date and then they were friends and now they’re flirting, giving each other hickeys, and he even got her a giant bag of stuff for Valentine’s Day (he’s basically taking it more serious than she is, for her this is fun.)

Okay so she’s been going to his house and hanging out with him for awhile until he has to go to work (he works night shift, meanwhile my baby daddy is at his house unaware of all this.)

Like she even gets mad that my BD won’t ask her back out even though she’s the one that dumped him for something that was thrown out of proportion.

Continuing with the story- She has this other guy saved in her phone under the name of one of her female co workers at her job so he won’t look for the text messages.

And she’s still staying at my BDs house and sleeping his bed, acting like everything is normal.

She went yesterday and bought her boy toy stuff for Valentine’s Day and was making jokes about how she should just get something they’ll both like and whoever acts right on Valentine’s Day gets it.

Now I really do love and adore her but here recently things like this have made me start thinking of her differently and I’m in a sticky situation, on one hand I want to tell my BD what’s going on because he’s my child’s father and I don’t like seeing him be done this way, but she’ll probably 100% sure know I’m the one that told him.

Or two continue letting her do it while pretending I don’t know anything with guilt eating at me.

I want to do the right thing, I care about them both but I just think what she’s doing isn’t okay especially when she’s jumped all over his ass for supposedly doing something like that when he actually hadn’t.

Sometimes I wish I would’ve never became her friend. And at this point I don’t even want to be her friend anymore.

**I never said he doesn’t want to be with her? I just said she’s mad because he won’t ask her back out because she tried to blame him for something that didn’t even happen.

He works literally all day long, comes home and sleeps, then gets up and does it again. He doesn’t even have the time to be shady even if he wanted to be.

**Yes I’ve posted this multiple times.🙄 Because I got no advice and I really really have no idea what to do in this situation! I’m stressing because idk what I should do.
