I'm married to a cis-straight guy. It can work but I'm a little concerned about some of the things you mentioned like him not being into your gender, him being heavily attached to his straight identity and not so keen on physical transition. there's not really much you can do to change any of that yourself, he would need to work on it himself. he knew you were trans so...I don't understand why he pursued a relationship if he was not completely comfortable with you being trans and what all that would entail? I worry that one or both or you may be sacrificing certain parts of yourself just to stay together. I wouldn't recommend making transition decisions based on a person you're with, especially for such a short period of time. Transitioning can be an emotional period for us...I'm so thankful to have someone who is there for me as I transition and is supportive. I couldn't imagine staying with someone who made me question it. I don't think it's fair for you to have this to worry about whether this person is going to lose interest in your body on top of everything else you're going through. while you may care very much about one another it's going to take a LOT of work on his part to move past this and he may never be able to(if he's 100% straight). You deserve to be with someone who is both romantically and sexually interested in you. You don't have to settle.
