Well, I've been with my girlfriend for around 7 years (we're both 28yrs old) and she's just told me she needs 'space'.
In general we've got a great relationship and recently things have been really good between, we bought a house 7 months ago and have spent all our time planning and renovating the house together, its been great. Just 3 weeks ago we were talking about marriage and kids; she said that if I asked her to marry me, she would say yes and we discussed having kids in around 3yrs time.
Now she said she's wants space because she met a guy 2 weeks ago (a friend of a friend) and they spend hours talking in a club and she liked him - nothing happened though. Since then they've been emailing and agreed to meet. She said she wanted to see how she felt because before meeting him she was really happy with us and couldn’t understand herself. Apparently, nothing happened on the date, she had one drink and told him she was happy with me and didn't want anything between them.
Now she wants space because she doesn’t understand how she can like someone else and go behind my back like that. She thinks this means we perhaps shouldn’t be together. She did cheat on me 3yrs ago (kissed a guy on a date behind my back) and we broke up for 7 months, but eventually came back together.
An additional problem is that we're tied into the house we bought and can't afford to sell it even if we split up - nightmare.
What should I do next?
