my best mate has all sorts of grief from his ex. they have two girls one is 8 and the other 5yo.
get the visitation rights sorted early, the rights for dads have improved greatly but if you dont do the paperwork now it will cause stress later, you will need to put in effort it sounds like shes being a bitch.

as for the rest of it it just takes time, bit of a hallmark card statement but its true bro

the route we followed with my mate a year ago was to get the job sorted sharp'ish it will built self confidence as it did with him. bit of money in your pocket goes a long way when you want to do something you can just go do it.
tesco asda bus driver whatever to start you off in my experience its easier to move between jobs once your holding a position however lowly it seems.

all the rest drops into place once you build confidence up.

ive been to the brink too, 11 years ago i thought the world had ended when at 22 i broke up with fiance, a 4 year relationship but known each other for much much longer.

took some time out, nailed a few chicks that offered while i was engaged, i declined at the time but with her gone why the hell not!

now years on have a nice flat, a couple of cars, top girlfriend of 9 years with a cracking rack lol

im also overweight and my hair is running away from my face, maybe me and Big-Dan should start a sub forum, anyway more support your way, times the healer
