Wot wud ya do if you just found ou you've been lied too?

This is going to be hard for you, you've been with him for 4 years and you probably love him very much, but you need to make a decision now about whether you want to tie yourself down to a drug addict who lies to you, who has mood swings and who you simply cannot trust. You could decide to stay with him and try to encourage him to change his ways, or you could quit now. Whatever you decide, it won't be an easy ride for you, if you decide to leave him there will be pain and heartbreak to deal with, if you stay then its likely you'll have to face more mood swings, deceit and possibly even violent behaviour. Give yourself some time and space to think about what you want your own future to be like, then decide accordingly, remember if you leave him now it may hurt like hell to start with, but time heals, and your future may be a lot brighter with him out of the picture. Good luck.
