How to see her everyday n still not express my feelings i used to do?

I m in a relationship with a girl(4 months long). Its kind of weird but her mom came to know about this. We talked with her once and here is the verdict. She says behave as true friends and dont be emotionally linked. I luv my gal a lot n she luves me more i knw. Her mom is not against us but upholdin her verdict is killin me. I will see her everyday in college but wont b able to hold her hands or hug her or kiss her. In short just wait until u build ur career n den get settled bt fr nw nothin. Plz help. Also i dnt consider movin on as an option although its just 4 months long. She is my soulmate. But hw to meet her everyday, see in her eyes, n still nt xpress.....
