Setting a Timeline with my bf? Am I wrong for this?

So my bf and I have been together 5 years. So my bf and I always talked about marriage and kids and all that stuff. Last year we sat down and had a serious talk about the next steps into our relationship. I asked him when does he see himself possibly proposing. He said “I WILL propose to u by the end of next year(which is this year now) or by the beginning of the next year. So maybe around September-March. I then asked him “are u serious because I’m being serious don’t give me some random ball park answer just to make me happy” and he said “no I’m being serious I already made up my mind. I thought about this.” So my bf knows the importance of marriage for me and how I have set goals and how I have a loose timeline for things. I say loose because I obviously know it can not be set in stone but I have an idea of what I want the next few years of my life to look like.

Before this conversation we had last year he always said he doesn’t see himself proposing until his little sister finishes high school. Keep in mind she just started middle school. Right off the bat I said “nope. I can not put my life on hold. That will mean we Will be bf gf for 9 years before u even propose to me.Nope”. So when my bf told me he will propose by the end of this year I told him “hey I’m keeping u accountable. If you don’t then I will have to step away from this relationship” I also said “marriage is important to me and I need to know that my time isn’t being wasted and I need to know that you are on board and want to take that next step. Hey we don’t need to get married right away but I need that next step. If not then I will have to step away. I have goals. Are u ok with that?” And he responded with “yeah I completely understand . I am on board and I agree with u it is time for us to take the next step soon. Don’t worry I will marry you! I love you and I already see u as my wife. I just need to make it official”. The only reason I gave my bf a “deadline” is because I am afraid that he won’t ever propose or move things forward because of what he said in the past about not proposing until his sister is out of school. I do not want to be someone’s gf for 8-10 years and never move to the next step.

So ever since our conversation last year he would sometimes bring it up and ask me what kind of rings I’m interested in and etc.. today he made a big purchase at work. He works as a diesel mechanic he needs to purchase is own tools. I completely understand that. But he already has a decent amount of tools for work and today he made a $1,500 purchase on a tool box and some other tools. I was a little taken back because he still paying off his first set of tools. I asked him “babe how long until u finish paying off everything?” And he said “hmm probably by the end of the year. But don’t worry ima get a raise soon.” Then I said “hey I’m happy that u got these tools for work. I understand that u need to purchase tools for work but hey u already got a good set. Did u forget the promise u made to me? I think it might be hard for u to purchase my ring when u already have all these other payments”. And his response was “this is an investment.” And I said “and am I not an investment to your life?” And he said “omg stop pressuring me! If you actually leave me if I don’t propose to you then that means you don’t love me”

Ladies when he said this I was a little taken back. Am I wrong for setting my goals with my bf?
