This can be a little hard to do correctly, so you may need to get someone to help walk you through it the first couple of times.
Failure to go forward is however one of the easier problems to fix.
Start untacked, teach her to lunge, you can start with just a halter-no round pen needed.
Start slowly just @ walk until, you standing still in the middle, can get a crisp walk off-use whip a good crack if needed- and whoa.
Than add trot, no need to canter @ this point.
Next do exactly the same with tack.
Remove tack and add a second line- it will run from halter/bit- along shoulder/barrel/hip and come around butt just above hocks.
Start by just going in the same size circle, re-establish your whoa and get a change of direction, gradually go behind horse so that both you and the horse are in a straight line.
Your lines should go evenly down both sides and end dirctly behind her where you are standing.
This is called long lining.
If you stay directly behind her, use your lines against her sides-take them out away from her-move your arm away from you- and bring it back against her side will give a similiar feeling to that of your leg, meaning forward.
Do continue to use your voice aids as well.
Add tack, do as above.
With practice you can long line @ walk/trot and canter.
Then to address a completely different point.

i huged her sides with my legs
Your legs should just hang natural, jello jiggler like.
Try turning your toe straight out, pretend that you have a spur on, and tap her with that back part of your boot. Then toe forward and soft relaxed leg.
Think of someone poking you repeatedly, if they poke and leave the pressure you would ignore it, but if they continue to poke over and over, you will move away.
Same goes for the horse.
A tight hugging leg, may be the wrong approach.
Good Luck
