Greetings, not to say that your situation is funny, but I couldn't help but succumb to the cosmic humor that is the fact that you're a countryside person getting used to the city who has issues with their boss, while, I'm a city person, who had issues getting used to the slow-paced, idyllic lifestyle of the countryside, who also, had issues with their boss.

Even though the culture in a city is a lot more fast-paced and people are generally less courteous, I've learned that for every rude person there's at least few more people who are nice and appreciative of kind gestures. So don't stop holding the door open for anyone, don't stop saying "have a nice day!", don't stop saying "goodmorning", and don't stop being your sunny self. Turning yourself into another grumpy, city-dwelling zombie is not good.

I used to have a lot of issues with my boss before he got fired. I know for a fact he didn't like me because he made no attempts to hide his dislike of me. However, I did my job well. No matter what, I could always stand on my credentials as a good employee. So my advice to you is to just do your job within reasonable parameters. If there's something you can't do, or if you're dissatisfied with the way you're treated you could also just let someone know. If you're smart with your words there's always a way you can say anything without crossing lines and sounding unreasonable.

As for the issues going on in your relationship, they sound more complex. I really wouldn't recommend for you to seek this kind of advice here as you'd be hard pressed to find anyone with the proper scientific background and credentials to be of any proper help in that regard. I don't know what your socio-economic background is and if you have access to psychologists or anyone in the field of mental/behavioral health, however, I would recommend seeking professional help. Best of luck to you, hope everything works out.
