Ur story is very touching. . . .
Seems u really love this girl. . . .
It's normal to not being able to trust. . . .
Have u ever thought of talking this out with her. . . .
I mean i understand taking the emotional stress of the accident must have been a lot to handle for her. . . .
Which is why her behaviors might hv changed. . . .
But if u r loosing faith in her. . . .
Then u should seriously sit down with her and ask her how she feels and tell her how u feel. . . .
I'm sure u guys will be able to sort it out. . . .
Wishing u all the best for it. . . .
Stay happy. . . . tc
