Sounds like there are a lot of issues.

One month is not that long in terms of a relationship, not much attachment other than what you state, the sex.

Sex is wonderful and in my experience sometimes can make or break a relationship.

Plenty of fish in the sea, try dating around, see each other on the side, who knows if sex is all that seems to be holding you there now, make the relationship purely sexual.

I’ve had two or three in my past, which were just that.

Nothing wrong there.
