I caught my husband of 20 years looking at inappropriate pics of women on TikTok or Instagram. I'm not sure., but when I told him he got mad and made excuses of why they popped up. I then told him how I've snuck on his phone and saw what he's been looking at . We had a horrible big fight. I asked him why did he even marry me when I see the type he likes . Nothing like me, I'm petite, blonde and blue eyes. These women are dark haired dark eyed and have curvy bodies, large breasts, etc. I just don't feel the same about him after this.
