Hi starblue,
On the pretext of your opening thread title, if your sentence is grammatically structured correctly then may I presumed that
(a) Person X is already your boyfriend.
If that is the case, I would strongly urge you to move on as X is definitly not worthy of your love for him. You deserve someone better. Let go.
Contradictory,
(b) if Person X is your crush
The first approach is to trash it out with the new girl because you have every right to fight for someone whom you truly love. I am not inciting catfight and hair pulling but to approach it in a competitive way since you are in the queue first.
The second approach is to give X up because it seem that he only wants you to be his friend, nothing further. My advice would be to drop him off your mind completely and instead to concentrate on what you are doing currently, let time heal as well as to sort out your thoughts on relationship further. At the same time, you are also giving someone deserving of your love to come into your life.
Regards
