Need Advice

New poster, not new to poker. Love the site, love the OOT. Got a question. I recently had an encounter with an older lady, very nice, gentle, she is like 45-50. Met her at a grocery store, I was gettin bananas and she whispered sweet nothings in my ear. I went back to her place and we [censored] like rabbits. It was awesome, but gross at the same time. Her fantastic chest was compromised by the not so great ass. Im in a relationship currently, I need advice. What do I do with the G/F? Should I consider seeing the older lady again??
