Fuck this is frustrating!!! I'm frustrated so I can't imagine how you must feel!! Actually, yes I can. You two are perfect for each other! You have the perfect set up, it's just lacking the sex. He has exactly what he is looking for in you, he is never going to find it in anyone else because he has it all with you!! It feels like you are both skirting around the issue, you are both not wanting to have The Talk. You have met The Prof so now PM has upped his anti in trying to bag himself a woman. Why? If that isn't a reaction to you meeting The Prof?
I wonder if he is as much wanting you to see his profile as you are wanting him to see yours? I wonder if he has seen your profile???????
When, if at all, are you going to face your fears and talk to him??
