my OH and I have a strange "arrangement" going on too. we split up at the end of june 2010. he moved out of the house i was living in, then moved back in because it was easier than trying to stay at his parents' house. the plan was for him to stay as a roommate for a few months while his house was finishing being built. its a house that WE had designed together, but 100% in his name. we became pregnant during those few months, so he said i could move with him so he could help me through the pregnancy. now baby is almost 2 months old and we're not "together" but we're not really separate anymore. we sleep in the same bed now, and dtd every now and then, but we don't act like a couple! i'm not "allowed" to kiss and cuddle with him, etc. but we get along great and he talks about the future with me included as a family. so i'm not really sure what the deal is. sometimes i kind of think he can't bear to send me away because i would be taking his little girl with me, but other times i think he wants things to work out between us. it's so confusing!
it really depends on the situation of your break up, and how your "relationship" is going as to whether or not it's a good idea to continue to live together. my OH and i were the best of friends and we both still love each other, and it's very easy for us to live together. but if you're only living together for convenience and it's stressful, and you don't see any possibility of a future together then it's probably best to try and work out another arrangement as soon as possible. you don't want to just get "stuck" living with him and being dependent on him with no way out. can you get a loan from family/friends or even a bank loan to get yourself out?
