I want so much to believe
OP you typed this in one of your posts and it sums up everything. You want so badly to believe that a lovely, caring, romantic life is going to happen with this man that you are willing to wait and see and excuse anything that happens. You will excuse away lack of intimacy, excuse away seeing each other one a week only when convenient for him and he gets no better offers, excuse away his investment of time and effort in another woman that he works with, who is married with kids and has no interest in him, excuse away his refusal of joint holidays so he can holiday with family or other friends, excuse away his offhand treatment of you as he is busy with "hobbies".
You come on here and make another thread with the same issue, you get the same replies from various posters all saying the same thing and still you excuse. You reply "but", "maybe", "what If" on and on and on.
This man is not the problem, your "relationship" with him is not the problem, spending no time together is not the problem, lack of sex is not the problem, the woman he works with is not the problem.
The problem is that I want so much to believe - you see things as you wish them to be, not for the way they really are. Until you see things as they really are, nothing will change.
