Hi! Thank you for replying! The house is not paid for completely. I bought the house in 2012 for $102,500. In 2015, he paid $40,000 to have the pool built. I spoke with a realtor and the realtor told me that houses similar to mine in my area with a pool, etc. are now selling for 220,000+.
We have a joint account which is used to pay the bills, we split the bills 50/50. If it comes down to paying him back for the pool, then I'm ok with that, but I'd like to avoid selling my house and giving him half. However, if that's what will most likely happen, then I don't see the point in spending more money going to court to be told that I have to give him half.
