My boyfriend only has girls as friends

So my boyfriend has texted this girl on and off through our relationship of 5 years. He was friend with her before we were dating and that fine. But I don’t they show text everyday. And plan movies dates and etc because they haven’t seen each in a while. I read there confessions and it’s nothing more than him encouraging and her venting to him about everything in her life and the daily things that happen. I see this as a problem because I do this with him because he is my spouse should she find someone to vent to every day any FaceTime and call?
