Messy situation

Long story short: My year long relationship ended five months ago, the last few months were long distant and tension was building.

I made the choice to end it cause I wanted the choice to do it so we could stay on good terms, I didn’t want things to turn nasty because I genuinely love the boy.

Fast forward, I’m back living in the same place as him but have just discovered he’s moved in with his new girlfriend despite them only being together for a couple of months.

I wanted to meet up with him cause we’d be working together for a bit but then we started arguing because his new girlfriend wouldn’t allow him.

Since I’ve been home I’ve heard rumours that’s she’s controlling, that’s she’s just his rebound and that he still loves me. And everyones talking about how weird it is them moving in together so soon.

I haven’t realised how much I missed this guy and how much I want him back until I’ve been back home and haven’t been with him.

Is it bad of me to want him back even though he has a new girlfriend?
