Hi
You have'nt mentioned that you are going through a divorce? But seem to be worried about the house. Nor have you mentioned about talking to her about how you feel. It takes two, and its great that you have both been honest about what you have done. Ignore what the family says or at least try to, especially if they are playing the blame game. But you both should be talking to each other. I know its hard at times and I know how you feel as i have been there myself, and your probably being torn so many ways. Im sure at times you dread coming home and worry about what your going to row about tonight as soon as you come in. But I'm sure your wife does too.
The advice I would like to share with you on your concerns you have raised is to try and stick it out in the house for as long as you can, not as a male thing at all - your probably thinking "its my house too and i pay for most of it" but do it for the kids. Only you can know what your going through, but whatever happens to you relationship, you will, i can assure you, feel better for staying in the house with the kids. It might even give you both a chance to talk. If things start to get heated, go for a walk or a drive, go see a mate or whatever it takes to swallow your pride. Rowing solves nothing when you get to this stage so don't if you can help it. Just walk out and let things cool down - your not running away at all.
Having the Police called is not good for anyone, I know I had my wife pull a knife on me, when I started to question her about an affair she was having when i found out about her. She got backed into a corner and I found out the easiest form of defence is attack, and its not nice. Even more so when my youngest at two years old witnessed it, and that opens up a whole can of worms with the social services (which i got blamed for calling - even though the police notified them).
She was arrested for common assault and of course things got worse after that. I was scum for calling the police but i'd had enough. In previous rows I'd been spat at, punched, kicked etc etc. But I stayed in the house for the kids. I even got accused of not being a real man because a real man would have left!! I did on occasion go for the evening or day but always came back or took the kids out for the day just to let things cool down. My ex threatened me with so many things like not seeing the kids again and taking me for everything, saying she was locking me out of the house and changing the locks when I left for work, all of which she cant legally do, but at the time i did not know this and i was distressed beyond belief. You can't be evicted from your own home if you jointly own it. But if you keep having the Police called a solicitor will latch onto this and might go for a court order to keep you from the house.
In realistic terms your wife can't have everything off you post divorce, but in view of her earnings she will probably try and go for a much as she can, unless you both agree amicably, its not her fault, it will be what the solictors will tell her is best, anything less weakens her position if you go to court. But if it does go that far, the courts will have to take into account your needs as well, you wont be expected to live in a cardboard box. Try
mediation or counselling before divorce if you have'nt already. Divorce isnt cheap for either side. The courts will look to protect the kids interests, and for a fella married to someone with a small income that generally means you'll get a percentage of the house when it is sold, and you might be asked to sign the deeds over to her. Unless you both have assets sufficient to support you and them too which you say you dont. Selling the house and dividing it up probably wont happen straight away nor will you find yourself having to pay two mortgages. But it depends on your circumstances. Currently I pay for my kids (20% of my net pay) she has a percentage of my pension, and the house is in her name. I get a percentage from the proceeds of sale of the house on one of a number of triggers (co habiting, death, remarriage or my children becoming adults) and i dont pay any of the bills, mortgage or indeed any arrears she has run up!!
Sorry for rambling on, but I hope it helped, like me im sure you want to do whats right for your children. Up sticks and leaving permanently won't, if you do go down the divorce route, and i hope you dont, doing whats best for the kids should be both your goals not whats best for either of you financially. You will be hit in the pocket but so will she and its a shame both sides dont realise this beforehand.
I hope things work out for the both of you...
