I've never had a good outcome from snooping someone's online messages I always regretted it after, in various ways.
Yes, this is my experience as well. I snooped in my moms diary once when I was much younger, I remember that what she had written made me cry, and it was so bad that I had to tell her I read it, so she could comfort me. lol. I learnt my lesson not to snoop back then, haha. Hopefully OP learnt his lesson now
Mom is a human being just like everyone else. She has desires n needs and makes mistakes too. At the same time I understand losing respect for your parents for such reasons. It is hard and confusing and completely sucks. But when it comes down to it its not your biz. No you will never see her the same but love her and accept her anyway like you would want from her. Thats what love and family is about.
