Well i think we can and can't blame him at the same time.
The MC is single that, essentialy, means no commitment, but that's semmantics at best and bullshit at worst. If your end goal is to find 'love' then you shouldn't be fucking everyone just because you can, it's going against the goal.
But at the same time, the MC only got closer romanticaly to two characters (Maya and Josy, the others are a work in progress yet... you COULD maybe squeeze Jill in there, but i don't think so), and let's say that Maya and Josy both aren't on good side of romance right now, they were cheating on each other after all.
So yeah, there's a liability for the MC to fuck everything, but it's going against the plan in the end. Mostly because the MC is not really trying to hide the fact that he gets around. So it will come bite his ass later in therms of romance.
