Are Angels allowed to fall in love or do they not have those kinds of emotions?

Thank you Rose  

I have come to understand that Angels are thought of as beings with unconditional love and often guide humans. It's just one of those thoughts that come. I suppose everyone might have different opinions and it is understandable and perhaps likely that Angels simply do not have those kinds of emotions. In terms of level, I'm thinking that my idea of love, well romantic love, may be not be exactly the same as the ideas of others. So I suppose to even answer my question, it also depends how we each treat the definition of "falling in love"
