My Sexuality

I’ve been thinking. I always thought I was a lesbian and only had feelings for women. But now I realise thats not totally true. And I think I may actually be BI. I like men a little, not as much as I like women but I do like them and have been with one man sexually a couple times in the past. In fact it is the friend I am visiting this weekend. No we havent been sexual. And we arent going to be. But I do like him and I think I like him in more than just a friend sorta way.
Does that make me bad? I mean I have a partner. But things havent been ok for us for a while. For one thing she is liveing in the USA. Long distance relationships are hard at the best of times. Add in to the mix that she is in in a residential psych unit and I dont talk to her often. And when we do talk I am always the one asking her how she is and I seem to be the one who worries about her etc. She rarely asks me anything about my life now or how I am or anything. Everything during our conversations centres around her.
My needs arent being met at all in the relationship. And it makes me sad because I really do love her. And I only want the best for her.
But all this has just made me think of my sexuality and how nowadays even though I am in a relationship it isnt really working out. And I dont knwow what to do.
Any advice appreciated.
