Well, you should have presented key facts up front.

Giving a gf presents every day is HIGHLY ABNORMAL. If THAT is what was going on, you need to RUN to a therapist because you have a web of unresolved issues. You need intensive therapy now. That you are still thinking of this a competition which you could have won is irrational, but that is not the most important thing. The most important thing is that you did not have a social circle besides those two people, that you behaved stupidly with the gf in financial terms, and that now you have no friends. The daily presents are so abnormal that what happened afterwards does not matter very much. What you need is not learning how to move on, but to engage in therapy to analyze what was happening during those 2.5 years and think about how you can protect yourself from getting into such mess another time.

To repeat - the problem is not in that you got dumped, but in that you put all your energy and money into the gf giving her daily presents.

If you read the forum called Relationships and Communications, you will see that people get dumped every day.

But I have never read an account of anyone who was showering the gf with daily gifts. Especially large! Especially on credit! You were insane. Your behavior was insane. Go to a therapist even if you need to borrow MORE money to pay the therapist, because successful therapy will save you money in the long run by making you spend reasonably in future relationships.

Also, and finally, giving daily presents is stupid. Even for your best friend (formerly and now a foe) who is filthy rich, giving daily presents would be extremely stupid. Presents given so frequently lose value and show desperation. Part of a gift's value is in how thoughtfully it is chosen and how special it is for your special gf. There is no way to achieve it if you give presents daily - the frequency diluted the value of your gifts to zero.

OMG, I have read SO many stories on this site, but you are the first man to report going into debt to give his gf a LARGE PRESENT DAILY.

No, therapy is a must. This is too complex.
