Dear twenty47,
I understand the situation that you are facing now. We can only
advise you not to accept another girl just because you are feeling
lonely, or you can't get the girl on the top of your list.
It is not only unfair to the girl, but to you as well. You will
never love the girl wholeheartedly, should you enter into such
relationship with this mentality.
Trust me, the relationship wont last.
However, you may wish to get to know the second girl better. Who
knows, you may even grow to love her in the long-run.
Good lUck
