Search Results: bored and annoyed

I've been with my boyfriend for over 2 years now. We are common law. I knew that his best friend was a female and they had sex once but that was it. They've known each other for 8 years. I am not worried about my boyfriend. I know for a fact there is no attraction whatsoever anymore from him. He's been through engagement and other serious relationship before me. She is the issue. In the beginning of our relationship, she already made me feel like she doesn't want to know me. Flopping events and never comes out when we ask her. However, almost every weekend, she asks my boyfriend out alone. Whenever my boyfriend mention that I'm coming, she just DISAPPEAR until next week she tries again. When we met, she refused to add me on social media. I told my boyfriend that I trust him, but there are red flags popping out all over her face. Whenever they go out without me, it doesn't make me feel any good. Over the 2 years, I talked to him about it many times. I believe that he has spoke to her that she needs to include me in events as well. For maybe around a month, she was better. But that was it. Now, she basically just asks him out. If my boyfriend is bored, he goes out with her. I'm not that happy about it. Thank god, it doesn't happen often. My boyfriend is pretty annoyed by me talking about it again and again. He's being oblivious about everything. "One of my friend told me that I need to be straight up with him. Tell him that I trust him, but, the fact that she's making me FEEL something is VERY FISHY makes me really uncomfortable if you go out with her without me. I would feel so much better and comfortable if every time she ask you out, you bring me with you and we will go from there. Unless I feel all her fishiness is gone, I would feel really uncomfortable with her. She thinks that I just never said it right. My friend told me because I haven't, it makes him feel like I will get used it. Do you think this would work?
