If he were, you would have asked him to accompany you to your brother's wedding, not the other way around.
Are you dating him exclusively? Or are you considering other options? If you aren't even dating him exclusively, you might want to let him know. Though if you've been going out since January, he has a right to assume that by this point it IS exclusive.
He is really smart. So I think we will be okay. You kinda know my situation, and I don't really want a steady boyfriend (sounds too serious) but he is great and treats me well and I am not dating anyone else.. mostly because I spend what little free time I have with him so I can't MEET anyone else!!
Still, if you don't want to introduce him to your parents yet, just tell him that you enjoy seeing him and what not, but that you are not ready to take that step. If he doesn't understand, he's probably a bit too insecure in the first place. That ONE point should be enough.
You are right, I bet so. Though since he is going to the wedding in June, he will meet them then. Better to have him meet them earlier?? Or would that be too much of a sign??
