Troubled Waters

My significant other was complaining again today. He/she was saying that he/she doesn't feel appreciated. And it's all because I spend time with other people. Have any of you heard of/done 'best friend flirting'? Basically it's when you're so close with your best friend that you talk and act in ways that would make others swear you're flirting or you're a couple. It may involve actually flirting, but you both know that the other isn't into you like that. I do it all the time and it makes him/her jealous and feel unappreciated. I'm starting to get tired of it and wonder if it's really worth it. And it's only adding to my stress, which I believe is partially causing my urges to self-harm. I did it again today and it only seems to be getting worse.
