Dating site?

Yeap. My lying/hiding/cheating s.o is up to something again. Intoxicated again, reeks of alcohol and looking at pictures or something on his phone. He told someone through talk to text have a good night. When I asked him "who have a good night is"? of course he played stupid/oh I'm too drunk don't know what you're talking about/you've got issues". I caught a glimpse of his phone when he was outside (he was on it) it looked like a picture in the center with a red border. Then when I opened the door he closed the screen right away. It looked red again. Anyone know what website/app that is? I am so sick of this shit. I should be able to go to work and not worry about him getting intoxicated while watching our child (which is not often but still, it should be never- get intoxicated when I'm there at least, which he does anyway sometimes) Always lying and hiding. He claims he only drank beer. Yeah I'm not effing stupid. I'm just so tired of being blatantly disrespected. First it was lying and hiding the phone when we first got together, talking to this one "girl". Then it was lying about drinking and hiding bottles, which it still is and now the phone is back. I really wish I would've been able to see into the future. I wouldn't take my child back at all- my child is my everything and I love them with my whole heart but I wouldn't have moved to the middle of nowhere. I know I'm dumb. I thought I found the one but now I feel stuck and it sucks immensely because he continually disrespects me. I don't want a custody battle or not be able to see my child everyday. I'm so tired..
