Friendship and Compassion

I've realized that that I don't feel much friendliness for a person which I considered my friend previously. At the level of friendship, things are not the same. Yet, this person has done nothing wrong against me. I know they care deeply for me, they value me, and they have a hard time making friends. Their life situation is also difficult. I would describe them as a virtuous person, extremely caring, curious spiritually. For me, it is only the fact I don't *feel* the friendship to be there anymore that detracts me. **In Buddhism, is friendship linked with compassion? Should I disregard the fact this person may suffer because sustaining the friendship would be untrue? Or, should I perhaps try to see things differently, and more compassionately?** Thank you
