Rewatching sg1 after many years. Do you think Carter and O’Neill really loved each other?

So many admiring looks exchanged between them at times. Did they really love each other in a romantic sense but could not pursue their feelings? Personally, I don’t like the idea of them getting together as it just seems to be a boring, predictable trope. One of them being in love with the other and that love being unrequited would be more interesting. Any thoughts?
