LONG POST- 
Today is my fiancé's birthday we have been together 11 years since we were teenagers engaged for 1 year, two kids DD 4y, DS 5m, yesterday night I packed him an over night bag and told him to give me space.
We have been in a pretty bad place for the past year, since I found out I was pregnant with DS last Feb we have done nothing but argue. My pregnancy was rough, my first child was very unwell and premature when she was born so my next pregnancy caused alot of strain and worry. I also suffered from gestational diabetes, my son was born 6 weeks early by emergency CS.
During this time and while my DS was in SCBU my partner argued with everyone constantly and pretty much spent the whole time saying how stressful this pregnancy/birth was for him. He also spent alot of money in that time without telling me and went out golfing and to the pub several times the first week DS was born due to 'stress'
We have been back and forth since then with vicious arguments and lots of bickering he works alot (im a SAHM) and does very little with the baby perhaps feeding him once a week at most, he has never done a night feed with either child. A couple of times I have threatened to leave unless he changed his attitude, helped me more with the kids and stops telling me everytime I am cross I am hormonal or overeacting. But I have no family here and no where to go .
The straw that broke me was I suffer from anxiety which i take medication for and am having a real struggle passing my driving test (driving makes me physically unwell and i have tried so hard to keep going with lessons). On Wednesday I was unable to complete my driving test as I had a panic attack. My fiance treated me very coldly after this when he collected me and asking me 'WTH happened' no comfort or care for how I was feeling and saying he don't want to continue paying for weekly 2 hour lessons as I don't need them. This kicked off a huge argument and I then told him to leave and I had had enough. AITA in this, he says I am over reacting and I have ruined his birthday but I don't think I am. I just feel that anyone whose partner suffered a panic attack like that and then treats them so coldly cannot love them properly if they cannot even hide their dissapointment for an afternoon and put on a face of support especially considering he took 3 tests and multpile theories before DD which i support him through.
It feels as though he took a terrible day for me made it 100 times worse and all about himself, I understand he was disappointed but I really had tried so hard to even get this far, it has been such a challenge for me especially with a 5 month old, and a 4 year old with special needs at home all day and keeping me up at night.
Sorry for the long post, I just wanted to get my thoughts out and clear my head with it all, I feel so confused about it all.
