Hi readers of Reddit. A lil backstory/context…. I am the Eldest daughter and child of my parents and also their certified therapist lol. My mum(F, 48) and dad(M, 49) were middle school sweethearts who got married after 10 years of dating and had me soon after. Now, My mum and dad have had their fair shares of fights but always seem to reconcile (with my help) and move on…. Recently I was going to the market with my dad and while changing the music on his phone I saw his barrage of open apps and lo and behold I see the one app you should not see on the phone of a married man of 25 years… the app that has a red background and a white flame in the middle (starts with a T ends with an R). Now being the complete unhinged snoop with lil regards for a moral compass… I go through his app and chats and yes things did not look great to say the least… he did make it clear that he was there for lust because he loves his family and has no plans of leaving his wife and children…. But hell if I didn’t feel like throwing up either way. Now the big question is… Do I tell my mother? But the big dilemma is that he is the breadwinner of my family and has been a great father. If my parents divorce…. My mum might not get the financial support that she deserves or will get after he retires etc. and while I am an adult my siblings are not and the custody can be a messy situation. Plus he is putting me through University at the moment and I want to be a little selfish and play the long game… wait for my siblings to be legal adults, get a stable living and then pull my mum and everyone out…. So AITAH

Edit: Right… umm they can’t really be exposed to STI’s… cause he is not physically cheating…. More like cheating via phone … how do I know this… LIFE 360…. And the money bit yeah I’m concerned cause it’s not just for my siblings but also for my mum… if they divorce…. She won’t be left with anything and she can’t work… so yeah I’m more concerned about money cause rn she lives in a big house with staff and chauffeurs and loads of money who is to say that those factors would be the same after I tell her… and she is an emotional person. She will break down and I can’t manage the fall out all by myself so yeah I wanna play the long game where I know she can leave with minimal damage and efforts and still live the very comfortable life she does rn and finally I am their child not therapist even though I’m doing a Psychology Degree
