So, split from husband 8 months ago. After 6 months of hell living in the same house, in different bedrooms, eventually he moved out to a friends whilst we sell the house. He pays less than half the mortgage now (only so there remains an equal equity split when we sell) and I pay the rest and all of the Bill's. Me and my teenage son (not his) live in the house until its sold. Relationship with husband is at it's worse ever state, particularly since hes been seeing someone else. I've been away for the weekend and have returned home this evening to find he's been staying here ALL weekend. Hes made a great effort in covering his tracks, tidied up after himself, taken all his empty beer cans (drink problem) but I noticed on my smart meter the heating has been on ALL weekend (I haven't even put the heating on yet) so I text him and he admitted it and said "what's the problem". I hate the idea that hes just coming and staying here whenever I'm away, having god knows who back here, and being so sneaky about it, it doesn't feel like my home. AIBU??
