My partner has been seperated from his wife for a year and a half they still do things as a family but this i feel is different. They have today gone on to Cuba for two weeks, sharing the same bed. He says nothing in it as they shared a bed for years when they were married and nothing happened. We don't live together just taking it slow at the moment, but this has really upset me. He says he is doing it cause he has just took vol redundancy so has some money ( the ex has paid her half) Should i be worried they will get back together so just enjoy my two weeks and wait for him to come back?
