Not sure how to feel??

Sharyan
So I already have one child.. She is 8 years old.. I tried with her father the whole 7 years we were together for another. But we fell apart. Now I am with the love of my life and we have been trying for 3 months now.. We are not sure if it's him or if it's me.. But we don't know how to find out. If you can help please let me know anything.. Thank you.
