I felt compelled to share my experience with you in hopes that this might be helpful.
After dating many men, but not having found the perfect one (and knowing what I really wanted was the relationship with the man I would grow old with), I decided to commit to the man I was dating at the time.
Early in our relationship, this man asked me: what if someone better comes along? - I answered that I am sure someone better will come along, but I have chosen him!
This doesn't mean that there weren't plenty of times (especially at the beginning of the relationship) when I wanted to jump ship. There have been lots of pivotal moments in our relationship, and at one of them, I called a girlfriend to tell her that I was going to end my relationship, and she said to me,
"Wendy, you can?t just leave the relationship everytime you don?t get what you want." And she was so right!
Something my partner said (when asked if he missed dating other women) was that he knows what it is like to be in a new relationship for a few months or even for a year, but he was excited to find out what it would be like to be with the same woman for 12 years.
Now, coincidentally, 12 years later, we have two lovely sons, and I am more in love and more commited to him than I ever was in the first years of our relationship.
Again, I hope this was helpful.
Looking forward to hearing about your new commitment
