<human>: Can you give me the gist of the text in a nutshell?

So reddit, some advice would definitely be appreciated here. As in the title, I broke up with my ex roughly 3 and a half months ago. It was a mutually agreed break up, after only a couple months of actually seeing each other (we'd been dating for 4 months before hand though). She was far too busy to sink time into a relationship, we only really saw each other two or so times a month, so it made sense. However, we were both quite upset about it coming to a break-up, as we got on extremely well and, at least from my end, there was definitely potential for something more long term brewing.

Fast forward to today where, after cutting all contact because of *lack* of contact, she messaged me completely out of the blue, just to see how I was doing. Completely reasonable, seeing as we were pretty good friends beforehand, so I thought I'd see where this was going. Turns out we got into a long conversation about how she's in a new relationship with a guy who completely isn't her type (her words), and that she can't see lasting very long (again, her words). She went on about how being happy and doing the right thing aren't necessarily the same, and a little about the philosophy of love (yea, philosophy is her thing). The kicker is that she even said she misses me, and sometimes still wears the jewellery I bought her.

So, long story short, it looks like I'm being set up as a fallback for when her current relationship seemingly goes south. Mainly because she realised what I did, that what we had was good, and now she's experienced something different, she wants us back together. 

The problem is, she's being incredibly vague about what she actually wants to happen, and I'm very conflicted as to if I want us to get back together. I really like her, and have thought about her a fair bit in the off-period, but I have no evidence to suggest she's got more free time, or is willing to put in more effort to a more committed relationship. And the fact she's only contacted me as a potential fallback is a little insulting. Please help!
<bot>: Ex gets back in contact after a while, seemingly wants us back together as new relationship is pants. Do I go for this or not Reddit?
