A little background, she and I broke up years ago and we've known each other since 12 yrs old. Ever since we broke up we've maintained an amicable relationship just like a long time friend would. I studied overseas in college but whenever I went back home I always made time to hang out with her once or twice (just the two of us). I've been dating other girls and she has been dating this man, who was her rebound guy after she broke up with me, for the last 5 years (it's amazing right? since rebounds usually don't last). A few months ago, she was dumped by that guy. Near the end of her relationship she told me how their relationship was so stale and they hardly act like a couple anymore. Throughout the years I also got the feeling that she was never really into that guy. She has always refused to acknowledge him on Facebook. There were many times when the guy tried to change her status to "in a relationship" but she always changed it back. Anyway, not long after that the guy said he wants to break up with her and that he has been close with another girl for quite some time.
Now the problem is once she was actually dumped, she went into full depression mode despite her earlier claim that she feels nothing for the guy anymore. She kept going on about (strangely) how she really loved him and would never let him go, etc etc. After a while though, she started to calm down. This past few months she has been talking to me a lot more frequent than usual. 90% of the time she's the one who initiated the conversation. She's also being way more affectionate than usual, laughing at even the smallest jokes and using a lot of emoticons when texting. I know she's trying to find comfort in me and being the good friend (and ex) that I am, I listened to her. The problem is occasionally she'd have an outburst about how miserable she feels and kept asking me if that guy would ask her back. This usually happens between 1-2 weeks period before she resorts back to her cheery self. It has happened many times over the past few months.
My question is, how should I deal with her? if I don't answer her it'd seem like I'm a cold person (which I don't want since I don't usually ignore her) but at the same time whenever she has that misery outburst she's been asking me the same stuffs. "Do you think one day he'll want to be back with me?", "Do you think he really has another girl" etc etc for God knows how many times and I would answer her the same things again and again. She seemed determined to move on, she has deleted her Facebook, deleted his contacts from phone, Instagram, Twitter, you mention it. She also said she'd never go back to him if he ever asks. She also constantly mentioned that she doesn't want the hassle of meeting another guy and starting from zero again, that she'd rather be with someone she's familiar with (is it a hint that she wants to be with me? who knows)
If you're wondering, no I don't plan on being her rebound guy. I did think about trying to date her once again since I've also just recently broken up with another girl but I'm still not set on this. If I'm going to date her again, I don't want to do it now when she's still on her broken heart phase. I have a slight interest but my feelings for her is mostly platonic at this time.
