My best friend of 15 years just got out of a messy 6 year relationship. They broke up & she moved back to the city we grew up in, and where I live. My boyfriend has been talking about marriage and has been hinting at proposing. My best friend has been making me feel guilty a lot lately and saying things like "I really need you to come over tonight so that I don't think about it". She's my best friend but I work full-time and have my own business on the side so I don't want her to rely on me for that missing piece of her life right now (or to just keep her mind busy so she won't think about the break up). I know that she needs me to be her friend at a time like this but I have my own life and I don't know how to tell her that I just don't have time without hurting her even more. Also, if my boyfriend does propose, I feel like I would be nervous to tell her for the same reasons. How do I go about this?
