You're not happy, it's like the center of every one of your troubles. Happiness. It's hard to find but easy to never let go once you have it. What makes you tick? What are the things you love?
You're in a new country, you have the comfort of a 6 month relationship with a girl you can't be totally honest with, and a past you are deeply affected by. But why? You had a relationship with a guy, and? So now you would like to find happiness and found freedom in a woman. Thats beautiful... if that's what your heart desires. I'm 26, I'm a woman. I've spent 8 years with women and now I'm trying to find a different path and connect with a man. My relationships were messy as well and yes there are times I run into old friends and I feel like crawling under a rock. But recently I've begun to see that every path is different in all of us. That every single thing we do makes us exactly who we are today... and we have a choice of making it positive or negative. I want to surround myself with people that love and embrace me for everything that I am... and cut the people out that don't. Or at least not offer them much of myself. It's not easy but its a choice that I have and that you have. I've lived in several cities over the past 10 years and while I've never been referred to as a foreignor I have however felt very much alone. I made a mental list of all the things I loved, no matter how simple and just explored those sides of me. I read a lot of books during those times. One of them was called "In the Meantime" by Iyanla Vanzant. If we aren't truly satisfied in every situation or relationship then we are just "in the meantime."
You seem like you feel deeply and strongly and are very much in touch with your inner self... don't be afraid of anything, let go if you have to and find what makes you smile. Keep you head up because confidence just seeps out of us no matter how we truly feel on the inside. So you were with a guy... its just something that makes you YOU. And whether you fall for a woman or a man.. they will love every part of you. The truth will set you free, old saying but something to remember
I'm a rambler... and I speak in fragments. sorry. just offering objectivity.
