Did I tell you I just left the woman I love?
Why did you leave her?
It's just best for me. I want to try something else and if it works out, fine, but if not, I'll be back.
That is a little cold. If you love the woman, you should try to work things out with her, not leave and expect she'll take you back.
Why would I give up this freedom for one woman? She'll always be there, anyway.
You don't sound ready for relationship. It's a little narcissistic to believe you can indulge in dalliances and assume she'll always be waiting. 
Relinquishing part of one's freedom comes with being in a committed relationship.
