That sounds a bit like a load of crap............you're placing the blame back on her. There may not be anyone to blame. Watching herself do what? Everything right, but feel that it's not good enough???? That's silly.
I agree, that if he's telling her flat out that she's not good enough, or making any kind of comment that alludes to that, then there's a problem. I don't see that here, though. First time real relationship, unsure of what to do, as all of us are, or were, and feeling that she's not doing a good enough job isn't unusual. Many of us have been through it.
For example, I was out of work for over a year. For part of it, I had a medical reason, I couldn't work. Then, the economy was so bad that I couldn't find a job to save my life. Not even the gas stations were hiring. As a guy, that was tough, and as a guy who's 34 and raised to believe the man supports the woman, it was even tougher. Did I feel inadequate, that I wasn't doing enough? Of course..........but I also had to realize there wasn't alot I could do about it. Regardless, I was very depressed, and had to get help to cope with it. Not that I wanted to, but I had to. In the end, it worked out just fine, and we're quite happy together. Still day to day struggles, but those are common. Given today's society of broken marriages, single parents, and an overall non-caring society, I can totally understand the feeling of inadequacy, that I'm just not doing enough for the one I love, even though what I can do is more than enough.
On the other hand, I got to cook, which I love, and clean, and do things for my girlfriend that she truly appreciated. May not have seemed like much to me, but it mattered to the person who counted.
