<human>: So Im a 25 [m] year old medical student. I have been having casual sex with a girl I work with for about 5 weeks. It was a no strings thing that was convenient for both of us but she has really fallen for me. It got to 'lets talk about this' time the other night and she said that she loves me and I have to stop this before it gets serious becasue she can't. Im wasnt really looking for a girlfriend but she is great. She is pretty, she is cool, she is interesting, and caring. The sex is great but most importantly we totally share the same values-OK I dont know her fully after 5 weeks but you know what I mean.I really like her, although Im concious that maybe I just like sex and attention, I need to get to know her more before I can really know how it is. Anyway, so why end it? Well she is 32 and has 2 young children. She knows that in 2 years once I finish Uni Ill be out of here. I want to travel the world and work overseas etc. And whilst she wants to too its not that easy for her for obvious reasons. The children see their Dad, she isnt looking for me to come and make dinner and tuck them up at night so its not a problem at the moment, It just seems inevitable that whatever happens, in a couple of years we wont be able to stay together. So Im sat here feeling like its crazy to end something thats going so good becasue of how things might be in a couple of years, but its also crazy to carry something on if it has no future.

Can you give me the gist of the text in a nutshell?
<bot>: Things going really well with a girl, but looks like its going to end becasue we cant see a future.
