Transition is just one of the many changes that couples sometimes don't make it through. Blame for this is often placed on the trans partner. But it's wrong to blame someone for needing to be who they are and/or for not being able to be that person sooner in a transphobic world.

And it's also wrong to blame the cis partner if they can't stay with their transitioning partner because their sexual orientation doesn't match up. There's no blame to be had there either. Nobody chooses who they are. Nobody chooses who they're attracted to.

Love needs to lead any situation where one partner is going through a big change. Love, compassion, mutual understanding and respect. If we have those things and use them, we'll come out the other side connected, even if the relationship changes into something new.
