I may have read this wrong but I am under the impression the OP has a mental illness and cannot distinguish between what is the mental illness and what is a red flag with his GF. My point is the red flag may very well be him and his inability to distinguish this. And since the OP admits this is a problem but gives no indication on what those “red flags might be with the GF” I think it is safe to say that a parent of the GF would be wise to be cautionary with a daughter involved with the OP. I would give the same advice if the gender roles were reversed.
A lot of people wonder if there is something wrong with them if they go through a very unpleasant set of emotions. The truth is, it is the people who are most convinced that the problem can’t be them who are most likely to have the problem. A paranoid usually doesn’t stop to consider they are paranoid. No, they KNOW someone is out to get them! Likewise, the worse someone’s dementia is, the less likely they are to wonder, “What’s wrong with me? Why can’t I remember what everyone else does?” No, the farther gone the person is, the more convinced they are that they haven’t forgotten anything and that their reasoning ability is just fine.
While some teens are stupidly confident and seem impossibly bold in what they are willing to try, the teen years are also the most likely to time in life to wonder, “Am I normal? Does anyone else feel this way? How can I make this choice for my life, when I’ve never made any decision that will really affect me for
my whole life!?! How can I promise to support someone for a life time…me?” The same young person can even go through both extremes of outlook by turn, being ready to change the world in one area, but not wanting to make any definitive commitment in another. This is not atypical at all.
I would say it is a red flag if either of these were true: If he found that this young woman made it harder for him to deal with anxieties–say, if being around her made it harder for him to believe he was going to get through some test successfully, rather than that she had a calming effect on him–or, conversely, if he felt so dependent on her that he didn’t think he could do anything without her. Not that he didn’t want to have to go through life without her, but that he didn’t think he could cope with the difficulties of life at all, unless he had her in control of things. Those two extremes would worry me, yes, especially the second one. That is too much to put onto one person. You ought to lean on your loved ones for support, but ultimately you ought to be trusting that God will get you the support you need, and not put your trust in a person as if that person were divine.
