I use to truly love a girl she use to stare at me with a smile
Did you actually ever interact with her other then an occasional staring contest?
but i am still confused was she in love with me or not ?
How in the heck can we figure that out considering we don't know anything about your relationship between each other as depicted by your very long run-on sentence.
How long did you know her? Did you date her and for how long? What country do you live in? If she really loved you and in fact had a relationship with you (if you lived in a developed country, regardless of her parent's pressure, she wouldn't have married for parental consent. This isn't the 1950's or earlier.
