You should look into getting interpersonal therapy, it always helps to learn how to interact with others.

In the issue at hand, you should try and communicate more with your current SO. Communication is key in a relationship, but you should also see the situation on the other person perspective. This is all good and dandy in words, but harder in application, that's why I'm recommending to seek help, it always helps to have someone that can analyze the situation further and help you grow as a person for you.
