i agree about the tough love tommy, but also try to find a bit of quality time for you & the mrs with out the child. see if you can rediscover your love for her but i will say this even though it may seem harsh if you and the mrs have nothing left for each other at all dont stay together just for the sake of the child because that never works and the rows will get worse until theres hatred and who nows where that could lead and you would not want to let your bab see you & mrs at each others throats . but if remember leaving must be the total, total last resort
never underestimate the predictabilty of stupidity
