<human>: 25/m. 3 years married. I think about leaving my wife every day. 

Ever since I became married, I've been plagued with lengthy bouts of depression, accompanied by feeling like life is a dead end. I'm not happy with where I am in life. 

Once the ring was slipped on, bye-bye blowjobs. I honestly have no idea how I didn't take this as a sign of things to come. Over the past years she has gotten fat, and I find myself less and less attracted to her. Looking at pictures of her older relatives and mom, I can't imagine myself being with someone who ends up like that. 

I feel like I rushed into marriage, going from college to wedding without any time to live on my own and learn more about myself. 

I have recently begun having homosexual fantasy and ideation, and am not free to experiment. I never got a chance to do so before I married. 

We have contemplated separation numerous times, and each time I can tell she trusts me less and less. She isn't the one who is unhappy, and frankly I'm just coming to think that I'm too much of a pussy to begin the process. 

Here in Canada, I'm aware that we need to separate first then divorce comes. I'm terrified of financial repercussions (spousal support, though we earn similar income and have no kids). 

I fantasize about living on my own, not having to answer to anyone, putting myself out there in the gay/bi community, being creative, active, happy. I am none of those things now.

What should I do to proceed? I am aware that I have to talk to my wife first, but what after that, should I move out right away, file the separation notice, get a lawyer? What're the next steps??

Can you summarize the given text in a few sentences?
<bot>: Married too young, becoming less and less attracted to wife, questioning sexuality, not emotionally invested in relationship but too confused as to how to proceed.
