I stay at her for 4 out of the 7 days of the week.

I don't stay longer at I need to spend time at the gym, and spend time with family and friends.

The thing is, I feel really bad, as she gets lonely living alone. She keeps saying how fun it is when I'm around.

She doesn't see her friends as often as she used to, she doesn't like them. And I sort of feel guilty because I've experienced being lonely in the past, and it Hurts.

At the same time I don't want to stay around, because it sort of removes the excitement of seeing her, and I've got other things to do.

What do you guys do in this situation?
