Re: Long Distance
Yes, you are not, and at the age of 20 many aren’t, so I generally don’t expect 20 year olds to be mature adults.
Your parents should have recognised this and not arranged your marriage this early on in your life. They also should have known about your insecurities and disorders, and known that you must come to terms with those first, before you can bear the responsibility of a marital relationship.
This has got more to do with the level of maturity, than the distance between the two of you.
