Husband (M28 F 26) been online sexting

I been with my husband for two years total. I been married a bit over six months. We have one kid together. Recently I went through his phone and found out the past two years he’s been on Reddit finding girls to kik, snap, and telegram. On top some were even getting married for pictures and videos. He’s on other dating sites as well. I found him trying to meet up with other girls. He claims he was doing all this when he was drunk and on drugs. I honestly feel betrayed as if a part of me is just over this. I saw he did it a few days after we got married. He claims it was all lies. What would you do in my spot? I think maybe taking a break or divorcing. I love him but I think this is too much.
