My boyfriend used to talk to girls ???

He used to like flirt and try to talk to a girl while he was on dates with me and I ignored it and didn't noticed! Now that I been thinking about the past and stuff I feel like leaving him!! He's too fucking nice of a person and I fucking hate that about him.. He will talk to anyone , even the waitresses. And one time he used to text his coworker and I found out she texted him and say I'm bored what r u doing?"I tried to brush it off and not get too jealous but now I'm extremely jealous and want to leav him now!!! Should I ??????😡😡😡😡😡😡😡 He basically gets me jealous and try to be "extra" nice to girls in front of me but that's not how life goes . What if I was talking to all these guys and being "nice" he wouldn't like it 😂😂😂pendejoo
