My moonflowers, which are related to morning glories, sent out new branches when the tops snapped off this spring. I've never pruned morning glories, but there's a chance they will do the same. I would carefully straighten the bent stems, and not cut them unless the vines began to wither where they were bent. Sometimes a plant can rebuild a bent stem, but it takes time and must be treated gently, like a broken bone. Either way I don't know if they will bloom, because I don't know how they behave in your climate. The vines will definitely need something to climb, otherwise they will sprawl on the ground and likely get stepped on by imbeciles. Can you put a trellis in that spot? A teepee made from three or four long sticks tied together at the top? Make sure to sink the poles deep into the ground, at least a foot down, so it can't blow over in a strong wind. I've had that happen. I've also had wind and rain rip vines off of poles. You may want to gently tie the vines to whatever poles/supports you use, to prevent this.

I hope this helps; blue morning glories are worth saving for their beauty alone, and it sounds like these have a special place in your heart.

Can you set a trellis of some sort between the plant and the wall then reattach the vines? If not I'd just cut the stems at the point where they've fallen away from the wall. They should send out new growth. I hope it was an animal or something that caused them to pull away from the wall. I hate to think it was an inconsiderate individual. Good luck.

Update: I followed your advice and tried to save as many stems as possible, carefully untangling them from the ones that were too damaged. Took a long time, and many leaves withered and are falling, but they are now sprouting new branches and seem to be doing fine. Also, I found out who did it and am planning revenge, hehehehe.
Many thanks for helping me out =)
