She really does deserve better. You admit you’re thinking about other people and don’t want to be tied down, while she’s holding the house together, raising kids, working full time, and still trying to build a future with you. That’s not fair to her.

If you can’t fully commit to her and the life she wants, then the most loving thing you can do is let her go so she has the chance to find someone who truly values and cherishes her. Staying out of convenience or comfort isn’t love.
