My mom is cheating on my dad and I don’t know what to do, should I confront her?

Im 61 (the number backwards) and l’ve noticed my mom being really suspicious recently and it’s a whole story but here’s a little in the things that she has change in her character or the way she act
1. She come homes late, I have her location and she works really late but I see getting out of the train and staying at a random house for three hours and then coming home and when I ask her if she comes directly at home she says yes
2. She is very protective with her phone which she wasn’t before
3. I found a bouquet of flower with money hidden really well on her closet and also a new guess bag which she kept hidden for a week and after that she showed it to me telling me that she got it at Burlington (that bag wasn’t a bag that she would usually buy or even her style)
4. I came home early and saw her cooking something (which is weird since my dad is the one who cooks the lunch so food was already at home) and she packed everything and took it with her and at night I heard a little notification or well that sound when u start voice recording something on your phone and she comes and asked me if I would like to try the food and something else and after she was done asking me i heard that she stole couce recording me (the food is not our traditional food from our country but rather its a food from other country from Mexico which btw the guy whom I think my mom is cheating with it’s from Mexico)

These things has made me realize everything that has been happening and I thought it was just my imaginations but today I saw my mom using her phone and I took a picture of her conversation and she was telling this guy “beautiful afternoon love..” and I checked the guys profile and it’s no one fro our family to say that oh he’s probably a family member Please guys help me I adore my parents and my mom but her actions are really fucked up and I don’t know if I should confront her
