am I a home wrecker / side chick

this is funny story. so me and this guy started dating last year when the eagles won the championship we made it official 5/24/18. I just found out he was in another relationship 5/13/19. when I say there were NO SIGNS! I slept over his house multiple times he’s slept over mine even met my daughter got each other birthday gifts and everything 🤦🏾‍♀️ but I called him 5/13/19 and a girl answered his phone so I asked where he was she said he was busy I laughed and hung up ( I don’t argue over men or fight over men that’s just not me he’s obviously not worth the drama) she then called me from her phone about an hour later with him and her arguing and I hung up. a week later she calls me from a total different number threatening me and my child (this is where I draw the line) so I said well come do it then ( she said she would be me and my child to death) she said “bye girl” and hung up. and never showed up ( she said she knows where i live) so this is the twist I don’t even know this girls name what she looks like or ANYTHING but she knows about me and calls me the home wrecker? he’s just now calling me saying sorry from a blocked number I just hung up on him. if I had known he was dealing with another woman I wouldn’t have even entertained him and for sure I wouldn’t have let him meet my daughter.
