Little rant on boyfriend buying a ring...

Okay so long story short last year my boyfriend and father of my three kids asked me to pick a ring from thw engagment rings on Zales so I did. I was all excited he bought it, told me when he went to pick it up, showed it to me that same day and let me try it on. So I thought i was gonna get to keep it from that day. Well this guy tells me okay put it back its your christmas gift... and Im like am what. It was the end of july. So I told him then why did you buy it so early and showed it to me just to tell me its my christmast gift. Fastforward to christmas eve he tells me sorry I fidnt get you anything for christmas We can go on a date if you want. And I asked him about the ring I thought that was my christmas present and tou promiaed it was gonna be under the tree. He then tells me he dosent think its the right time. But it will be very soon. So me being stupid though hey maybe valentines day. Valentine’s comes around and he tells me sorry I didnt get you anything so Im like okay fine whatever. Im bugged but eventually get over it. Then my birthday.. then mothers day... and I ask here and there hey remeber that ring thats just sitting there on top of the dresser and he is just like yeah I dont think we are ready for that yet. So why did he buy a ring 🤦🏽‍♀️🤦🏽‍♀️ in the first place and showed it to me and then just not go theough with it Now its almost going to be a whole year and he just keeps saying the same thing over and over. He can have kids with me but not go through with marrying me? Even though he keeps saying that he loves me and wouldnt know what to do without me. I feel like I just keep giving and giving and I dont get the same from him. I dont ask for material things or anything for that matter. I dont want to be all pushy but it has been putting me in such bad mood lately just thinking about it.

UPDATE

I dint know if anyone is gonna read the update but here I go. I talked to him about it told him if he wasnt ready why did he buy the ring and that its a really stupid game he is playing if he dosent want to marry. He said he is ready and does want to marry me BUT he dosent know how to do it in a nice romantic way and that he works so much ans never has says off to so anything like that. I just stayed quiet because I dont know if Im thinking too much into it but for me that seemed like another excuse. Herr is why when he wants something he like obsesses over it nonstop he will research google and talk to his mom and friends about it. We share the same google acount to whatever he searches it comes up on my google search history and trust me there is alot of everything on there but nothing about this. Also he does get days off he just gets them every two weeks he works for the post office so they are extremely busy but he still gets them and he rather spend his days off playing golf, sleeping or with us going over to his family. Idk but I think Im just over it. Its not about the ring its about marriage and he dosent seem to take it as serious as me so for the next few days Im gonna think over if this is actually how I want to live the reat of my life or if I should just leave. Right now I just feel like it will be leaving...
