My question involves collection proceedings in the State of: PA

My ex boyfriend used my credit card to pay for books, computer equipment and other items with out my knowledge. When I got my credit card statement he said he would pay me back. We have now been broken up for 7 years and I keep asking him for the money. I am fed up with him now and I wish I would have pressed charges when I first found it on my statement. Has it been too long for me to do anything about it?
