Reality is that a lot of people have prejudices. That does not mean that their prejudices are correct and does not mean that you are obligated to agree with or share their biases. It does mean that you may find some people in your family and circle of friends that are incapable of accepting and/or supporting you. So you have to decide who you want to share this part of yourself with.
As for relationships, let me suggest that, right now, the last thing you should be thinking about is the next relationship. Get used to being alone and give yourself a good deal of time to get settled and recovered from the end of this relationship. Time in terms of many months, or better a few years, before you rebound.
