This is a complicated situation but there are pretty easy ways to handle it as long as you do so in a gentle manner and treat the situation as it is, sensitive and complex. First of all, you are always to respect your parents, this is a given. However, with that said, parents are also supposed to love and support their children no matter what as well. Given their religion and their beliefs it really isn't a surprise that they feel the way that they do about your sexual identity, however, their beliefs and feelings are just that, theirs. They do not have the right to belittle or degrade you in any way shape or form or make you believe that you are any less of a person because you are gay. You said that you are nineteen, and although you live with your parents and have to respect their rules while in their house,you are also old enough to make up your own mind and decide who you date. If your parents are so against this part of your life and refuse to accept or acknowledge it then don't bring this into their home or their lives. If you and this guy are truly in love like you say that you are and if being apart is hurting the two of you then be together. Just do it away from your parents, Prehaps over time they will come to accept this and then you can truly be open with them but for now, their beliefs seem to be gaurding them from approving this, however, this doesn't mean that you should lower yourself to being unhappy or without love just to make them happy, after all, they are your parents they are not supposed to make you feel the way you claim that they have. My advice is to get back together with this guy who you say makes you so happy, never pass up love. Just don't flaunt it around your parents or expect their acceptance for awhile. People need time to adjust and accept things on their own terms, you can't expect them to accept it as easily as you do because parents have a preset version of how their children will turn out pretty much right from the time the child is born, so, to be told after nineteen years of living the preset version that this is actually not how their child will be living his/her life is a shock to any parent, and increases with parents who have intense beliefs. Give them time, maybe they will come around about it when they do see how happy you truly are. One way or another the only one you have to worry about making happy is yourself. When you are happy you are content and when you are content you will never have to wonder about weather you are doing whats right because you will just know.
