My one year olds father is a great dad, very attentive and wants to spend as much time with his son as possible. We havent been together since our child was about 2 months old. I ended things because I didnt feel the same about him anymore and he always used to fib about the silliest things, which led to me not trusting him. He has had alcohol problems in the past and gave up drinking when we were together. He now goes out drinking from time to time with his mates but says its under control now. something I believed until yesterday. He came to pick up our son yesterday and I smelt beer on his breath. He said he had one beer the night before at home and that was probably why. However I could tell by the way he was acting that he was lying. My issues- one he was driving my son to his house that day, two im worried he has a drinking problem and three he lies to me which worries me in terms of my son. advice please. x
