He hates himself for who he is and she loves him for it.


so true.
Also Sam turns herself into who she thinks Jason wants and needs in his life. IMO Jason was always an easy target for Sam. She knew what to say, what to do , and how to get to Jason. For Jason , it was always about Mikey and Sam knows that. Also Sam was so "high" on the life when she was living it with Jason , but when he broke up with her and she found out about Liz and Jake suddenly Jason was a "danger" and cost her everything. She hated Jason and would never go back to him, yet here she is again. Back to right where she was before only worse off and she doesnt' even realize it cause he is settling for her and not the life he wants.

Always said from the beginning Sam was "conning" and using Jason to get a life for herself. Sam wanted the life Jason could give her and she didn't care about anything else.
Jason was like the "trophy husbands" she conned....only she never got the ring.
