...after i explained to him that it hurt my feelings he didn’t take me along... ...he told me his parents want to meet me. i can’t help but feel there is a catch. is this a good idea?
There may or may not be a catch, but more importantly is, DID HE ADDRESS WHAT YOU TOLD HIM? I think that the disjoint between what you say to him and moving along without him addressing any of it is what's making you grow insecure. He might not even notice that he's doing that.
One of the things that I have learned about a LOT of ex-JWs is that they refuse vehemently to think, acknowledge, leave alone talk about feelings. Talking about how any of you feel might be challenging for him. Him wanting to introduce you to his family seems like a sign of good commitment, but I have the feeling that letting things unanswered may start creating insecurities, then resentments, then other escalations.
That said, please keep in mind that what I posted is my guessing on a relationship between two people I don't know.
I wish things between the two of you grow well enough so you don't feel the need to inquire outside.
Best wishes.
