Am i really out of her?

Last year i had a breakup

Later came to know she is moving with some one from her office

Now even though im willing to move with some one in my life but im not getting those intimacy feelings and physical arousals

Even in my imagination she is the one with me for those things and during our relation i get really hard erections by just sitting beside her or holding hands together or having a casual or romantic talk with her or when ever we are very close and some times i feel pain in my balls due to long erections

Note: we never involved physically

Can anyone suggest me some tips to come out of this
