<human>: Can you succinctly summarize the text in 1-3 sentences?

We've been together for a bit over 2 years and recently we have been going through a rough patch because even though he loves me and thinks we have something special, he's not sure anymore if he's *in* love with me/wants to be in the relationship. He's having a hard time articulating his thoughts, so I'm mostly in the dark about this and it feels pretty shitty. We're trying to fix things and we hope to see a counselor, too.

Problem is, he's made a new friend, and I can't help but be jealous since I'm insecure with the state of our relationship. Every time his phone lights up and her name pops up I feel jealous even though I know I shouldn't. I've never had any issue with him having female friends before, but I don't know her, she has come into his life during our rough patch, and she's also really pretty and seems cool :/

How do you deal with jealousy like this? I've only ever really felt jealous for fleeting moments before, but now it's everyday and it makes me feel like I'm becoming the crazy girlfriend and making our rough patch rougher. I've talked to my SO about it a bit but he just says it's silly and that he's focused on fixing what we have. I can't help but think he's going to break up with me and move on pretty quickly with his new friend.
<bot>: SO and I are going through a rough patch. A new woman comes into his life and I'm feeling jealous and insecure. What do I do?
