You have to work together and continue to communicate. There is no other way to resolve these problems. Ask her why she doesn't want you to touch her. No one else knows the answer. She also is the only one who knows if she is seeing someone. These issues can be dealt with through a counselor but she has to be honest with you. Until you have the truth then nothing else will work. Start with asking her why you can't hold her and if she is seeing someone else. You have no other but to try again.
