Hi there,
First of all if you are already committed then why are you here asking for guidance if some one is offering you....There should not be any confusion if you are committed!!
Why do you need to give in to your hormones?
You are 30 and the girl is 18, who is matured here? You or her?
If you are so much committed with your girl friend then be loyal to her even if 100 numbers also offer you... That's integrity!!
But, if you are getting confused with the 18 year old girl then you are not loyal enough to your girl friend.... Is not it? Think over it...
Next Steps
Consult myself on telephone and have one or two session of counselling your confusion will be solved.... Book appointment now...
