There is an old saying; “If you want to know me, come and live with me”, and I think this applies here greatly.
It sounds like things were easier for you when you could return to your own space.
But now that you are living together, there is nowhere for you to go in order to deal with her attitude.
I’m wondering how it would be if you sat her down and spoke to her about what her mood and attitude is creating in your relationship.
Do you know of any incidents in her life that may be causing this? And if so, has she ever explored talking to someone about it?
For now, reader, you need to focus on what is best for you.
Look at your relationship and identify the positives and negatives.
The most important thing in a relationship is balance and if that is not there, then it needs to be examined closely.
It’s your partner’s choice whether she wants to work on her issues or not but you too have the choice and responsibility of doing what is right for you. I wish you all the best.
