Search Results: making love or having sex

I started dating a girl several months ago, knowing I would leave town within the year. Because I will be gone and may never move back to my hometown, we mutually decided that we will end it when I leave anyway.

Recently, I have begun to notice that she has become lazy in the relationship. While I cook, clean, buy groceries, etc., she comes over each night to eat, drink and have sex.

What keeps me from ending it just yet is that while the sex is just ok, I love having her over to watch movies and study together. In addition, she doesn't have a good living arrangement and I worry that without me, she will have issues making ends meet while attending college.

While I am about ready to end it and am set to leave town in a couple months anyway, but was wondering if I should just end it now or wait it out.

For the past few years, I was in a relationship with this Mormon girl, and we had a pretty good relationship. We'd have difficulties when she'd doubt our relationship because I wasn't Mormon, but we made it work.
But she had decided to do a mission, and I asked her to marry me. She said she'd say yes when she came home, but she started to push me away. She said she couldn't marry me now because she went through the temple, and she'd stop saying she loved me. She also asked me to see other girls once she left.
I walked out of her place one night because she was making it so hard on me. Later that night, my ex messaged me asking if I'd like to come over and have sex again because she was going to move away soon.
Despite all the issues I was having, I told her I couldn't because I still felt it'd be cheating on my girlfriend, despite everything going on.

Should I have done something with her? Or did I do the right thing?
