Yeah but even as fck buddies Alex was a jerk, he never really show any form of respect toward DG, who was more a body pillow than a friend with benefits
True, but they weren't friends or even friends with benefits. If I remember correctly he told him it would be just sex. That's it. A booty call. Though I agree he could have been more respectful. Though I might be biased to Alex as I have been in one of those relationships. We didn't hang out or go anywhere, when/if we were single and "lonely" we would call each other. We didn't go on dates or hang out. Purely physical. The only thing that was promised was that we didn't call on others. Once either one of us thought of starting a relationship we let the other know and that ended it. Until things ended and a simple "Single?" text was sent. Of course safety was a must and that type of relationship isn't for everyone.
For me the problem with Alex wasn't that he wanted a no-string-attached relationship: in this he was perfectly right and DG was in the wrong. The fact was that Alex was a shit to DG. Their physical relationship was a mess not just because DG was in love with him, but also because Alex had a very toxic approach to it. He used the fact that DG was a pushover to do whatever he wanted and I think he liked that DG was so infatuated with him because he would never oppose him and he would always had the upper hand. I really like these chapters not because Alex is suffering, but because the dynamic is reversed: DG isn't gonna follow him like a puppy anymore, while Alex is slowly becoming more and more aware of his affection for DG.

Ok i know some are gonna disagree with what i'm gonna say but i just have to say this.
I don't think it's fair that so many people put the blame on Alex and want him to suffer. He is a jerk, yeah we all know that. He could've been more nice with DG and not act like a total jerk BUT.... but beside all that it's not his fault that DG fell in love with him and got hurt. Alex said from the beginning that all he wants them to be is friends with benefits. That's all he wanted and he warned DG that he shouldn't expect anything more from him. Yet DG didn't listen and fell in love and suddenly started to expect Alex to be more and more like a boyfriend to him. He wanted more and he got hurt and did something very stupid. That's why i don't think people should want for Alex to suffer cause he's so horrible and all that. It's clear this guy loved someone and got hurt. He doesn't want this to happen again. So yeah, that's all i wanted to say. ( actually i had more but i feel i wrote too much already...)
