Me! Kind of kidding but I am also half serious.
I always invest time in new friendships: I call at least once a week to check in, I invite them to lunch, buy coffee, always ask if they need help with kids, dogs, chores, etc. I try to be helpful in hope they will notice and appreciate it. I think I am also generous with my money, I buy friends birthday/holiday/just because gifts and I can't say that anyone I'm close to is that generous because I rarely get the same from them. I think many people I know are cheap, or frugal, whatever you call it.
I am good listener.
Unfortunately, many friends I've met over the years, sort of decide to disappear on me once they get married, have babies, move away or just become busy. Of course, having low self-esteem, I would like to think it's actually me.
Somebody who I feel comfortable with & can him/her anything without worry I'll be judge. But it takes more than that & I'm not sure what.
I have a friend who I know does not judge me and has seen me at my very worst, yet she is not the person I'd call at 3am. Not sure why or how to make it possible? We've been friends now for nearly 6 years & it's still 'let's get the kids together' type of relationship. Even though she was a major support during the worst time in my life.
