I am new to mumsnet and really my first post here is me hoping to find a way to turn. I am 24 and have a DS who is 2, I have been with my DP for 7 years and over the last year things have began to turn sour. I'll try not to ramble on into too much detail but will give you the basics, my DP changed jobs just over a year ago he met some new people through this job and began using recreational drugs. Since then things have gone downhill so quickly. He started to get mood swings, sometimes being nice then suddenly getting sullen and moody, snapping at the slightest thing. Then came the laziness, when he is not working he hardly gets out of bed/moves of the sofa and never wants to go anywhere with me and DS and once DS is in bed I am on my own until he comes home around 11pm, and hardest of all he doesn't help out financially anymore, he provides me with a car (shared) but I am now left to pay rent/mortgage bills etc on a part time wage! When I mention this he threatens to leave me and I always hope he does, however I am scared of being a single mum taking on extra strain plus having to fund a new car that I have to have for work. I'm not looking for sympathy but perhaps just some advice from people who have been through separation before, and someone to talk to.
