Just for a bit of background, DH and I are both 30, have been together for 10 years. We have 1 DS who is 3.5 and I am due DC2 in May. I've always suspected he had some sort of MH issues due to his anger and other behaviours. Possibly has ADHD but his mother never bothered to get him diagnosed as a child and he doesn't see the point now. He is NC with his entire family due to DV between his parents and towards him as a child and general lack of effort on their part to maintain a relationship with DS. He has a good job now, however has job hopped for a couple of years as he's never been happy. He seems happy where he is now. We have been under a bit of financial pressure for the past year or so due to him job hopping and taking out loans behind my back to cover any shortfall when we wasn't earning much. However, this is looking better now he is on a good wage.
So he was diagnosed with anxiety over a year ago, started talking therapy but stopped going after a few weeks because he thought it was useless and he refused anti depressants. He seemed to feel better for a bit but now thinks he is depressed aswell and has been back to the doctor who has referred him back to therapy and advised to start antidepressants. He's said he will think about it and has to go back in 2 weeks if he wants the prescription.
In the meantime he is absolutely vile. Horrible to be around. He's snappy, shouty, angry, detached, doesn't want to talk to me, doesn't want to play with DS, doesn't want to do anything really and I just can't cope with it. I hate being around him. And I know I don't sound very supportive but I'm pregnant and tired myself and having to look after and entertain a 3 year old. I've been supportive for the past 10 years. I just don't know if I can keep doing it. I'm drained. He's exhausting. And I know it's the depression and he can't help it and he can't think about how its effecting me and DS (all his words) but I'm just fed up and I shouldn't be feeling like this when we're having another baby. I'm turning into someone shouty and angry because of him. I'm scared. I'm worried about how he will be when he's sleep deprived. I'm worried he just won't be interested at all and I will have to cope alone (had this a bit when DS was born). I'm also worried about how its effecting DS...I haven't told DH this but DS has been saying things like "daddy's not my best friend because he always shouts at me" or "why does Daddy keep being horrible to Mommy?" and he's been extra cuddly and loving towards me which is unusual because daddy is normally the favourite and doesn't normally want me when he's upset etc. He's also started waking up crying in the night the past few days and I'm concerned it's because of DHs behaviour because he's never done it before.
Either give me a good talking to and tell me I'm being ridiculous and unsupportive or just some advice on how to approach this because I feel like I'm going to have a breakdown myself.
