Hi, haven't wrote on here in a while, just been a lurker ha ha.
Anyway, i need help with something so please honest opinions and advice.
Recently met an amazing guy on an online dating site, to cut a long story short it's like dating myself we're so alike.
The snag is i have this horrible feeling that he hasn't read my profile properly and doesn't know i have kids. The reason is, he hasn't asked about them, nor have i brought them up. How can i bring this up? Should i do it over the phone or to his face? He likes kids and works with them and tells me how much he enjoys it, but i'm scared he will run a mile. Yes i know, if he does, he isn't worth it but i feel so connected with him and he seems really keen too.
So it's either he hasn't read my profile properly, or he just isn't bringing it up because i haven't.
I'd rather it be the second option but need to prepare myself for the worst, so how can i bring it into conversation? Should i do it over the phone? Or to his face? I'd rather do it face to face but he lives an hour away and would feel bad if he came over just to leave again.
Please any advice to stop me stressing....
