Was i love bombed?

Hey guys I just came here just to vent because I really have nobody to talk to about it and some positivity would help because all I want to do is cry right now…. So I have been single for a VERY long time now and the healing process has just been up and down…. I met this guy who was treating me SO well from jump and eventually I started bringing my son around and he treated him even better… to sum it all up cause I don’t want to explain IT ALL again…. I was basically just being used,. He’d do things for me , buy things , for me and my son. express how much he was falling for me 24/7 damn near love bombed me … I think I WAS love bombed because I noticed after everything he’d do/ buy for me… there was an even bigger favor he would need…. Or money he needed to borrow and after a while all the lovey dovey started dying down and I honestly already started to feel used before the major problems occurred…He wasn’t acting the same towards me anymore once I started doing things. I just found out a few minutes ago he was still with his ex the entire time. She said they’d been together a couple years…MIND YOU GUYS I met his mom and many family and friends that all know and have been around his ex as well …. I’m just confused to how could someone’s own family be so fake and be ok with knowing he was lying like this and I also had a conversation wit the ex we both were very much being lied to . Told her he didn’t know me… told me she was “messy” and always trying to ruin his new relationships… lol my trust for men is completely gone
