@JohnnyAppleseed1 I hope the concrete discussions with a third party help! I applaud your patience and good will toward your girlfriend and hope everything works out the way you hope it will.
One thing: Without attacking your girlfriend for it, but speaking as another woman (and just so you’re aware and not overwhelmed by guilt), I agree with the commenters who pointed out that your girlfriend seems to be, whether subconsciously or consciously, using your guilt to manipulate you. I’m not discounting that to some degree her tears were real (especially if she suddenly felt afraid she was about to be dumped) – but the words she added to them were manipulative, designed to get you to reassure her, pity her, take care of her; basically, her words were designed to suck you back in.
The truth is that she may
not be what you’re looking for. (That is, in some ways she is, but in other
crucial ways, she isn’t.) It’s just a hard reality of life that sometimes this happens; if it’s the case, it doesn’t make you a bad guy.
And I would ask you not to be bullied for a
second by the accusation that your poor explanatory abilities sap her interest in learning about Catholicism. Yes, it’s good for us to learn and improve good apologetics skills. But if your girlfriend wants to hear a perfect apologetics explanation of a Catholic concept, she can seek one out herself. She’s presumably a mentally competent adult. She has internet access. Let her know that
catholic.com exists. Maybe connect her with some other solid educational resources. Then if she feels you explain something badly, it’s still on her to have the good will to try to understand
you, by seeking out the
best possible version of what you were trying to say, not dismissing what you did manage to say as ‘So inadequate I won’t even look into it further’. If she loves you, she can seek to educate herself about the relationship with God that is at the centre of your life. Full stop.
Anyway, maybe she just had a little mini-breakdown (we all fall into manipulative language/behaviours sometimes, especially when we feel vulnerable), and this was just her wakeup call and now she’s going to start actually trying to learn about your faith. So I’m not suggesting you “call her on” any manipulative behaviour at this point, if she just had to get it out of her system in her momentary state of fear. Maybe she’ll really be open from here on out to learning about Catholicism, especially with a third party present. Maybe this is the beginning of a path to a healthier relationship.
