Angela,
Have you talked with him about how you are feeling? If you are engaged and have been together for a while I would try to work things out. If, however, he is ever physically or emotionally abusive, then it would be a different story- if that is the case you can do much better and I would seriously reconsider the relationship before you get married. I would tell your fiance that you are feeing hurt and ignored and that his short temper is hurting you. That you love him but you have concerns about your relationship. Hopefully he will listen and treat you better. Best wishes.
Kate
