Complicated relationships

Hailey

My ex of 2 months who I was together with off and on for nearly two years and I still act like we are together, we've communicated we aren't, and that we are just friends but we spend a lot of time together, help each other out and still have sex.

I've since been communicating with another man, someone who started to pursue me, started off innocent and then became flirty and now the conversations are a bit sexual, with him expressing the desire to go on a date.

Although my ex and I are not in a relationship anymore, because we are still so close, emotionally and physically, I can't help but feel bad and guilty about entertaining this other guy. I'm conflicted on telling my ex I'm speaking with other guys, but we aren't together, is it his business?

I love my ex and we split because of fundamental differences, not because we don't love each other.

My friend has said that continuing this complicated relationship with my ex is holding me back, that I need to part ways with him entirely to move on with my life. Regardless, I'm technically single but can't get past this feeling like I'm betraying my ex..

I would really appreciate some perspective and insight! Thank you!
