I (M25) found out my ex girlfriend (F24) is a cam girl, does that mean she was one while we were together?

Throwaway cause I don't wanna die.<br><br>My ex girlfriend and I dated for 2 years. In early December she broke up with me to go back to her old city and be with her family. The reason I'm broken up with is because I wasn't taking our relationship seriously enough cause I was too busy with work and council stuff (I was on the student union council for my Uni).<br><br>I had no idea she was going to break up with me at the time. Everything was fine. She even stayed with me for a month (early Nov to early Dec) before she moved back home. While she was here she had a lecture once a week. On those days she would leave my house at 8am and I wouldn't see her for a few hours. She told me she was at Uni all day but I now realise she lied to me. I just thought she was grabbing coffee with friends or something.<br><br>She would also sometimes leave Uni early to come see me. When she did I would give her money to pay for a taxi with and we would meet at a shopping centre. She would always be ready when I got there. She always had her bag with her which I also thought was weird seeing as how she didn't have anywhere to put it while she was at Uni.<br><br>I just assumed it was a weird habit of hers, but I now realise she probably didn't go to Uni at all on those days. Sometimes her lecture would get moved to a different day of the week. When that happened we would sometimes hang out together all day but she would disappear for a few hours in the early afternoon. I assumed she was just in the loo or something. Again, I now realise she probably wasn't.<br><br>I was talking to her old flatmates from when she used to live in the city and they told me they sometimes heard her having sex with men in her room. I assumed this was while we broke up but they told me it was before that, while we were dating.<br><br>It all made sense once I connected the dots. The days she would be gone from 8am-3pm on "Uni days" she was probably with a sugar daddy. When it was a normal day and she was with me while I was at work, she was probably having sex with someone in her room. When we met at the shopping centre I would give her money to pay for her taxi with. I now realise that money was probably to pay for a hotel room she was going to spend the rest of the day in having sex with a guy. I also now realise why she always had her bag with her when she left Uni.<br><br>I confronted her about it and she was like, "yeah, I was a sugar baby for a while." And I was like, "for how long?" And she was like, "not long." Which tells me absolutely nothing. I said "I don't get it, why didn't you tell me?" And she was like, "it's embarrassing." But like, she didn't tell me at all. I feel betrayed tbh.<br><br>But the main thing I'm worried about is that she might have still been doing it while we were together. The last time she had lecture was sometime in October. She broke up with me early December so if she was still a sugar baby in October and she was only in the city once a week for Uni, it's possible she was still seeing men in secret while we were still together. Not to mention we spent the whole month of November together at my place and she would often leave the house to go to the shop. While she was gone she might have gone and fucked some guy in a hotel room I know nothing about. That's what really gets me.<br><br>So, if she was a sugar baby in October (early Oct not late Oct), is it possible she was still doing it in early December? The fact that she won't tell me the exact timings makes me feel like she's hiding something. Is there anything I can say to her to get her to be honest with me?<br><br>EDIT: I feel like people are focusing on the wrong thing here. I'm not a prude and while I'm not happy with the idea of her being a sugar baby, it's not something I'll hold against her. What I am upset about is that I feel like she lied to me about seeing these guys while we were together. When she was my girlfriend. Yeah, it sucks that she was with other guys but I can deal with it. What I don't get is why she lied to me about it.
