One way to develop and maintain a positive attitude in relationship is ...

@ASilentObserver Reminded me of negative self-talk ruining my relationship with myself. So if CBT is supposed to help me remove negative self-talk, and improve the way I see myself, I suppose the same would be true of my relationships with others - if I'm always thinking negative things about those around me, I may be adding toxicity to these relationships without intending to. I suppose if negative self-talk is hard to unlearn, this may be just as hard to unlearn.

One possible risk of overdoing this might be making myself blind to abusive relationships, and blind to problems that truly need resolving

@ASilentObserver

At my eyes I think the best way is to focous on my self esteem.

Many people ignore that, and their insecurities are projected into the relationship and to their partner.

Is very hard to focous on myself, but I do my best. I want to love myself before anyone else does.

Communication and sharing your thoughts, I think it's so important to have good communication with a partner, you should let them know where you are, who you're with and what you're doing when you hang out with others, you should also be brave and communicate in an adult manner things that concern you this can deflect confusion and arguments in the relationship

So, What is one way to develop and maintain a positive attitude in relationship?

The method I use is to let go of my insecurities and self-doubts, just release them. I was not able to do that before this relationship, but now I can. I feel much better for it, and hope to continue this way.
