He hasn't been handling all the stuff with Jane very well, however, he has to be given some slack and some credit. First, this is affecting him too. He was locked up for weeks, thought he was going to die and it was all down to his step-son who he had raised as his own. Then he thinks his wife is going to die and then after he tells her he is wanting to and ready to start a family with her, he gets the carpet pulled out from under him again. And before all this he was dealing with Lucy and her psycho boyfriend along with the mental torture of Steven making it look like Cindy was back from the dead.
Also, Ian hasn't had the greatest time of it growing up. He had an emotionally detached father, he was treated like the runt of the litter, his mother married a man he couldn't stand and who treated him like dirt, his mother was beaten by this man and as a result left, then she died. The women in his life have been far from supportive. Especially Cindy, who Ian took back many times and did try to do right by.
So now he's got all this with Jane and I honestly think Ian doesn't have a clue as to what to do. He feels guilty because of what happened and he's trying to figure out a way to keep Stephen out of their lives forever. And you can't tell me he isn't torn also because part of him still loves the kid. And when he does try with Jane he starts with the way most any guy would, with flowers and a card. Then he gets shut out.
I really feel for both Ian and Jane in this situation. They are both dealing with so much and neither of them really knows how to handle it. Jane said some very hurtful things to Ian about Grant and Ian is just helpless on how to help Jane.
Yet, somehow, no matter what, everyone just hates Ian again. Poor guy can never win
