Would you ever forgive your parents if they have abuse you?

I can't say I was abused per se (I wasn't beaten or sexually molested). But I feel as if I was neglected. I am my parent's only natural child. My mother had severe complications which resulted I'm my being born a month later than I was supposed to have been and her not being able to have any more kids. They adopted another son and he became their "golden child", I was pretty much pushed to the back which has carried on to this day. It's too long a story to go into here. To top it all off...my father made a sexual pass at my wife. He "invited" her to tag along with him while he checked on a neighbor's house he was looking after and while there tried to get her to show him her breasts. She was afraid to tell me about it but thought it was something I needed to know. I confronted him with it and he admitted to doing it and said he was sorry (but I feel it was sort of half hearted and that he was more sorry he was caught). I have been struggling for years to build some kind of relationship with them and I decided to forgive but it hasn't been easy at all. It only further strained my relationship with them and so I don't know what the final out come will be. It's a constant struggle within myself... trying to move past it all yet there are always reminders. I just keep trying to take the higher road and put it in the past...let bigones be bigones and move on. LIke I said, it's not easy.
