her kid is 6 

She has a son and doesn't have many friends to play with. We went to a yard sale and she saw an old neighbor. he told her that he has a son now and she didnt know that. She kept reiterating that he should come over and bring his son (5yo). 

I think maybe he got the wrong idea because he got her instagram and is only liking her selfies. maybe im seeing this wrong or overreacting but i know how guys think. he probably is seeing this as some kind of opportunity.

my gf did not include me in the hangouts that she was making until the very end when she noticed she left out. then she goes or maybe we can all hang out. she had brought up the playdate 3-4 times before she mentioned me. i was a little hurt and told her how i felt.

she called me delusional and said i need to rethink the situation. 

i gave her a heads up right now that it might get weird or he definitely got the wrong idea. she said if it does get weird, she will delete him.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: told gf maybe she shouldnt invite guys over with their sons. told her how i felt excluded and she called me delusional
