My partner of 3 years has a history of cheating online. After I had our DS I found out he’d been messaging and video calling women online throughout my pregnancy. We had therapy and tried to work through it. During this time I trawled through his internet history as I needed to know everything he’d done. I discovered he has a “type” of women he was interested in and interacting with, generally slim young women aged 18-22 with a “geeky” look. Since the cheating I’ve periodically checked his phone and found he also looks at these kind of women on social media and porn. We are 9 months on and he just got himself a job at a college where he is surrounded by women of the exact age and appearance he has been seeking out online. I am so anxious that he will cheat on me with someone he meets there. He says I’m being unreasonable, am I? I just feel if an 18 year old woman of his exact type comes onto him, it will be too much temptation for him to resist. I am 34 and can’t compete with an 18 year old in terms of physical appearance
