Okay, so what exactly is wrong with "if she wants to hear from me she'll call"? Isn't that kind of... proper?
Agreed - especially since she's blown him off twice without actually saying what's up. That seems like a strong sign it's over. Faye and Dora are just Charlie Brown'ing him again, for my money.
Nah, I don't think it's a good idea. Marten is so caught up in his pride, he won't make an effort to talk to Padma (as in, try something other than the phone). This is at his own expense since now he's in a position of uncertainty and deliberately put the ball in her court. He couldn't deal with uncertainty in the past, and now he's setting himself up to be screwed over and get all resentful again.
I don't think Marten's given up emotionally on Padma yet. He says, "If she wants to see me again, she'll call." Clearly there is an issue which needs resolving here, but Marten expects Padma to have an epiphany and change her behaviour, without Marten changing his at all (i.e. by trying another method of confrontation.)
EDIT: Setting her up to fail a little bit? Not sure.
Not that Padma is Marten's responsibility, but his behaviour could be interpreted as self-centred. Padma's in a way more vulnerable position than him. She's looking into the face of the 3 big triggers of mental illness: moving house, moving job, and loss of a loved one. It always seemed to me that Padma was really struggling with these changes, especially with her last-minute feelings for Marten. Marten immediately assumes that she's decided she's too cool for him, and that it has nothing to do with how much her life sucks right now. By letting her be responsible for contacting him, he gets to blame her when she doesn't, and withdraws his support for her at this difficult time.
...Or Marten finally talks to her, it turns out she just kept forgetting to call, and she's just like, "Woops, soz."
