Oh… I thought there was a question here. I guess you wanted to just say it? Well, if you ever want to talk, you can send me a message. Otherwise, if the person you have a crush on doesn’t have the same sexual orientation, it’s not really likely for it to work out. However, sexuality is complex and people have had exceptions before… and between straight and gay there are pansexual people and bisexual people. I think it’s a question of what you want and how badly you want it. If you are ok with a short-term relationship and she is too then it’s up to you how to proceed. But if these feelings are hurting you, then taking a bit of a distance from her for awhile would be best.
I’ve come across at least one queer (female) cousin couple on CousinCouples.com
Maybe it would help to talk to others that have been through it personally.
