Looks like a similar red-sleeved arm, or is it arms, reaching in the Pope card, and the man in the middle surely resembles the charioteer.
Could be a choice between a girlfriend or a parent or an adulterous quagmire, though, I think it's possible for it to also represent a group of friends and the love necessary to exist in harmony. While it's not called adultery when friends break up, or co-exist in a group, it seems to me it can be just as complicated and painful.
And if you think of adultery as giving a disporportionate allegiance to something other than one's betrothed or God, I think it could work for the internal workings of an individual who puts his/her goals or happiness aside for a lesser reward (whatever one's personal temptation as compared to one's path is). That is how I see this card for myself sometimes. I suppose cupid aims for hearts, but if I didn't know any better I'd almost think that hand reaching for the heart might be the target of that arrow. So, yes, I agree that sometimes love involves the choice of not choosing.
Yet, even if he doesn't ignore or leave both if it is a love triangle, I think it's possible for him to lead a life of integrity eventually if not simultaneously. The charioteer certainly looks all business and seems to have reigned in that emotion, but he is looking back, too. It may be his armor helps safeguard something within in addition to protecting him from exterior assaults and arrows, cupids or others. Also could be he needs or needed that experience to become master of himself. What is master of one's self? The deliberate stepping back and recognizing what decision to make based on one's inner code whether that code be intuitive or handed down from an institution one accepts. A constant trial and error period is the only way I can see to establish this code unless one chooses blind obedience. All of those various ways contain opportunities to exhibit love though they may not all be recognizable to everyone.
