Here's that question

What a coinkydink! I didn't vote for any of your options, because the most important thing for you to do now is to take a breather and do some long, hard thinking. I wouldn't necessarily call off the engagement with your current BF, nor would I meet the ex, just yet. Can you sit down and evaluate -- objectively, and unemotionally -- just what it is you love about your fiance, and perhaps even more importantly, what's drawing you back to the ex? I know that's a tall order, but it's very important. The happiness of three people is at stake. You owe it to yourself and to the guys to make a rational decision here, one that you won't regret too terribly much (I think the occasional twinge of "what-if" is normal, and allowable)...If you get married, your whole heart and soul need to be in it. If you're going to see the ex, you..must be aware of what you are risking...Good luck, and take care...

Scarlett rules !..

Ah, you've got a double parked heart...
Why did you break up with your ex? And do you not love the guy who just proposed to you enough? Do you want to spend your life wondering what if?..
There is probably a reason you broke up with your ex. Think about whether you want to throw away the guy with the ring. When all your ex did was call. (And I'm assuming you've been broken up for a while since the new guy has proposed.)..

Yep, listen to ScarlettO, you need to take time out to figure out what you really want. I wonder did..your ex hear that you had just been proposed to, his timing is just bloody perfect. Seriously though, if his phone call casts any doubt in your mind, you need to figure out what feelings you still have for him. It probably entails meeting up with him (always a dangerous venture) but if these feelings resurface it's better to get it out in the open now rather than when you're walking down the aisle. ..
Only time, and good judgment can help you decide what you want. Don't be hasty to run back to your ex either, why is he only contacting you now? What happened in the past? You were happy when your fiance proposed, why does his phone call change this? Your ex obviously hurt you before, could he do it again? Take your time, breathe and hopefully the answer will come to you. Good luck...
