This randomly popped into my head, and I would love your opinion. G seems to always need to be in a relationship – if you buy into her jumping right from Mark to David. I think maybe PM started to pursue her and she threw that in David’s face. Maybe at the end of that Schmoopie Shirt weekend she told him ‘I have someone who wants to be with me AND he lives in my city’ hoping to convince D to move to be with her more, but David called her bluff. (1/?)

(2/2) Only she wasn’t bluffing and got pissed and ended things jumping right into 🐢. I don’t know why, but I have a feeling D and G are both very stubborn and I can seem them falling apart because of this stubbornness — neither wanting to seem to needy or vulnerable. So maybe 🐢 was never meant to be something serious that’s why it always seemed awkward in the beginning, but now she’s afraid to be alone so she’s with him. What do you think? Could this be a possibility or am I crazy?!

I guess it could be a possibility. Why not. I guess we will never know so as long as none of them tell us the real truth, every opinion are valid. 
Personally, I think what happened might have been a little more serious than PM just happening to be there and Gillian taking any man who just lived there instead of David. I don’t see her ditching him just because someone else popped up.
But I agree with the fact that they’re both very stubborn and if the universe is telling Gillian that her significant other is David, she’ll try everything in her power to get away from him before she gives up and gets back to him again and again and again until she gets it for good. I also agree that PM isn’t that serious and probably just a rebound. He won’t stay around more than a few more months. Gillian has patterns…
