There is a quote from a famous writer, who said that a writer should find and marry a wealthy woman.
In more contemporary times, you might try for a particular market. Are you in your 40s, or 30s or 20s? This makes a difference in terms of your potential mate demographics.
Older (western) writers are likely to find single, divorced women in their 30s, and who likely have a child, and are of some if not full means. If you're a character of savory habits, but limited means, there is an improved probability that this type of woman will be willing to make a compromise. Age and experience has generally made them more practical and less air-headed about their 'list' of potential mate characteristics. (And women everywhere always have a 'list', and usually a long one).
You might have to lift your game a bit. Excessive coffee drinking is no good for the health or your demeanor it seems. Are you fit and healthy? Not overweight? Though, if you are an older writer, living in the US, based on the current US population figures as regards weight, there is a very good chance that you are overweight. Younger US women are less likely to be accepting of this factor.
If you're fit, healthy, not overweight, not shabby in presentation, then you might start hanging out at gallery openings and exhibitions. Seems a lot of women (older, single divorcees) spend quite a bit of time in the arts field (besides women generally). It takes effort, this mate seeking business. You should have numerous possibilities as to how to obtain your objective, and as a writer, it need not cost an arm and leg.
One of the things I would suggest you do is go and read some of the hundreds of books written by women for women on how to get a mate. No, really. For all our simplicity that equally so intrigues and exasperates women, we men generally have too few avenues or ways to put ourselves out there.Other than the regular tried and true 'male' ways. But, women have been doing it for centuries, and have learned more ways than men.If nothing else, reading about this from a woman's perspective will open your eyes, and perhaps give you an insight of how to do things differently.I would strongly suggest you go to a public library for this material, being in keeping with what I presume are your limited means.
Being a writer of limited means is not looked upon so kindly in numerous countries - you're a bit behind the eight ball already. A little change in the packaging and presentation, and repositioning, might both be necessary and work wonders.
Good luck!

ETA: The alternative, the so-called masculine way, is to learn to 'just get on with life', and 'take it on the chin', and not worry so much about one's independence. This might be a good thing, learning to live within one's own skin, as one is. It takes time, but it can make for a surer character. And certainly, it can help in putting out the correct vibe. As a friend, more successful with the ladies than me, once said, women can 'smell' your loneliness and/or desperation. There is a grain of truth to this. Women also experience this, but they are generally better at disguising it.
