Trying to decide between what we want and our family/cultural expectations is a age-old but very real dilemma. At first blush it sounds so simple - do what is right for you and let the family expectations go and that may ultimately be the right decision. If you decide to do this, though, you will have to deal with feelings such as guilt and that is the hard part. In time, you will probably come to terms with it.

If you decide to move back to Asia there will be feelings to deal with, also. The rub I see with this decision is that the feelings of resentment, regret, etc. may be deeper and more permanent.

Best wishes in finding your way. Ask for support in this when you need it.
