Hi. I don’t know if I can give advice, I’m not the queen of telling the truth, especially if it will hurt someone. I’m married and I have jealousy issues at times, so I know how she feels. If asked a direct question, I always tell the truth, no matter what. I would be upset too if you sat in the same room and text’d sexual comments to another woman, what were you thinking? You need to first explain the situation to your gf like you did in your post, but maybe a little more sugar-coated. Remind her that you two are friends too, but she is the one you are in love with. I love it when my husband refers to me as his best friend. You remember back to the time when you were trying to get her to be your gf and start wooing her again. Relationships start hitting bumps around 3 years usually, and then again at 7, etc….
Is your gf friends with Mandy? If not, maybe introducing them would help. I would also remind Mandy that it is inappropriate to text naked pics of herself. I have more male friends than female and it would never cross my mind to send a naked pic of myself, even to the ones that have seen me naked. Something is up with that. Maybe Mandy wants more than friendship. If I were you, I would get the girls together, so your gf knows it’s no threat, Mandy must bring a date. Then I would tell Mandy to stop sending porn over her phone.
This is just an opinion, and the advice might not help, but it can’t hurt can it? Try to be extra nice, and get a job, and that means anywhere, sounds like a big root of problem too. I went from running my own business to working at a warehouse, took a $15 per hour pay cut, and would take a lower paying job if it meant keeping my self respect.
