Need opinion....

My girlfriend started using the ring again and has agreed to commit to me. The bad she said she will stop comunication with ex boyfriend when she is ready. She calls him every now and then when I am not there and has marked in her calendar his birthday.

She said she is 100% mine and wants to be with me but wants space because supposedely, I am drowning her by not giving her space (NOT TRUE) but I agreed.

Question: IS this something I should worry? Will she ever get over him? Do I need to do anything? confront him? Let him know whats happening? let him know we are engaged?

I wonder if everything will be fine if she will be able to move forward with me and forgeet about him. We havent even had intercourse since we are back, she is very loving with me and shows lots of affection to me. But no intercourse, is this a sign she want him?

What should I do????Opinion on all these questions greatly appreciated.

Thanks,
