I have never broken up with anyone before. I am 25 and have had only one long and meaningful relationship before my current one and she broke up with me. Anyway, I knew this girl a year before we started dating and this August it will be 2 years dating. We moved in this past May. We are talking about getting married and buying a house but lately I am having second thoughts. Things have changed a lot since we first started dating. Things have rapidly become complacent. I have always tried to dress nice and look clean but she has gained a little weight and always wears the same loose clothes now. I don't care about weight but it seems like she does not care about her appearance anymore when I still try to look decent at least. There are more important things like the little things that I used to find cute are annoying now. There were things about her that I knew about before we started dating and I thought would change but now I see that they are not going to. Plus, her family likes to party loud, drink and smoke while my family is more reserved and does not get loaded at parties very often. I am laid back and quiet while her whole family is loud and I don't think I fit in very well. My family and hers have never met but I doubt it would go well.
So we moved in and bought a new couch, coffee table, end tables, and dining room table and that is the stickler. We still have about 9 months on the lease and all this furniture we bought together. I have never broke up with someone at this stage in a relationship so I don't know how to divide up the funiture and move out. Plus, I am not 100% sure I want to split. There are times when I am just fed up and times when we have a great time together. She is very committed to me and very excited to spend her life with me. I know she cares a lot for me and I am not sure if I match her feelings 100%. How can I handle this? If I do decide to end it, how do I go about dividing things and moving out?
