You might want to be careful about posting issues concerning your relationship online like this. Your girlfriend might see this page and be able to figure out that you posted it, especially since you describe things about the relationship like:
You met her in a park.
She, at one point, had a fight with her mom and had to stay at your place for a few days.
You and your girlfriend have been together for almost a year.
Your girlfriend has good hygiene.
Your girlfriend has bad breath that just won't go away, even after she brushes her teeth. (She may be well aware that she has this problem. She may just be hoping you haven't noticed. Sometimes people hope for unrealistic things when it somehow involves a romantic mate. Or, if she does assume you've noticed, she may just be hoping that you don't care. She may be afraid to bring up this quality to you.)
If she happens to see this page, she may strongly suspect it is you and that you decided to post something about y'all's relationship online. And, if she assumed that, she would be right in this case. She may then get mad that you said she had bad breath in an online forum with people. She may be upset that you brought up a concern about your relationship to some people on an online forum (random people you don't even know) before you brought it up with her.
I'm on your side, my friend, and I want you to succeed in your relationship. But I want to give you this cautionary note, so you won't get into trouble in your relationship. Be careful. You never know when the thing that is unlikely to happen somehow happens and she sees this post and suspects you. Just be careful, amigo. Best wishes to you and your girlfriend in y'all's relationship.
