I decided to look for an apartment and live on my own. I told my BF last weekend, and asked him to go with me to view the place that I was really considering living. I think it woke him up a bit, and I received a check for the whole amount he owed me that same day!
So he actually had the money available to pay you back, but didn't think it was important to do so until you decided to move out? Huge red flag. Please don't get me wrong; I'm really glad you were able to get your money back. I think, though, the manner in which it happened sheds a lot of light onto his priorities.
So long story short is I got my money back and found a place to live all in the same day! I haven’t broken up with him, but will not provide any more loans, and will also continue to monitor our compatibility going forward.
I'm glad you'll be able to move forward with your money, in your own place, and with an eye on whether you two are compatible for the long term.
