Do you consider this cheating what my gf is doing ?

She has a best guy friend who took her out to dinner and he paid. She's met his family and apparently they love her. Then he took her to yogurtland twice and paid for her yogurt. I've told her I don't feel comfortable going out on dates with other guys and then allowing them to pay. She was like " well you're always busy and I never decline a free meal". I'm busy working 2 jobs because I was saving up for a surprise birthday gift for her that is gonna have her in tears. Plus I gotta save up for a car and my own place cause I'm tired of accepting handouts . She's the type of girl that likes a lot of attention . She's like " it's fun to have a crush even if you're in a deeply committed relationship with someone whom you love". Huh? The way her and movie theatre dude exchanged glances was more than just friendly. He has a thing for her
