Unsure if my boyfriend (27M) is committed to me (22F)

TL:DR I’m not sure if my boyfriend is committed to me based off his actions and things he’s said

My boyfriend (27M) and I (22F) met 7 months ago. We had broken up twice already. We just got back together for the second time. I had asked if he could share his location and he said he won’t. He said he feels uncomfortable doing that and said it made my anxiety worse. Which he willingly gave me his location in the first place. He was always open about it. There were times where I removed it and he would share it right back without either of us saying anything. He kept it on when we broke up the first time. He turned it off the second time. He has broken my trust before I found out he was messaging a girl and planned to get drinks with her. That’s the only thing I found out about but in general I still have a hard time trusting people and he’s not willing to help build trust. He said i have to learn to trust and if I can’t then I have to find another way to.

Another thing which I know might be small but over the second break up he changed my contact name to just my name. He had changed my name in his contacts the second week we met to “princess” and it stayed like that the whole time even during our first break up. He specifically showed me my name was saved as Princess in his phone to show he was committed. He won’t change it back now. And his reasoning for it is in his words “I’m no longer infatuated. Honeymoon is over now two real people are dealing with each”. He was saying how we can’t erase our past problems that we’ve had but I don’t understand how my contact name has anything to do with our past problems. My whole issue with this is he used my contact name as a sign of commitment when we first met and now he’s acting like it was meaningless and only because he was infatuated. And the whole location thing he was so open about it the entire relationship and now after our second break up he has an issue with it and refuses to share.

There are some other things he has said that makes me believe he’s not committed. Before we got back together the second time he said he would give this another shot to see who I am when we work on things, if he doesn’t like who I am we go our seperate ways. During the second break up he’s admitted I’m comfortable and familiar to him. He’s afraid of unfamiliar things. He said his feelings decreased for me over time. He only said he would give it another shot after I asked if he wants me to give up. He said he’s committed he said we can only build and work on things together. But he’s not working on things with me. He’s just expecting me to trust him while giving absolutely nothing. Him not meeting me halfway helping build things and build trust makes me believe he’s not committed this time. I don’t want to give my trust to someone who in the end gets to decide if they stay or not based on whether if they like who I am
