Should I trust a guy who spends alone time with his female friend?

I have been on and off with a guy for over a year now and I feel used and disrespected when he picks to spend time with his female friend that he knows only 6 months longer than he knows me, doing activities together that they both enjoy. Some activities involve taking a road trip to another state together and staying over night for a couple of nights at a hotel. He claims they are just friends and not sleeping together and doesn’t understand why I am jealous. And apparently there is another female friend that he also claims to be just a “friend”. Currently we are “not together” however he still gets his “benefits” from me. He says he wants to be single and did tell me he doesn’t love me. However did say he enjoys how I make him feel and likes to spend time with me too. Doesn’t want a commitment. My feelings of course are involved and I do not know what to do. Advice? Opinion?
