Is it true that love is limitless?

I think it is or more of I HOPE it is. I love this guy and idc if its just infatuation. I love him that I like I'm willing to stay committed to him until we are both ready to be together and feel mutual about each other. Right now we're not on the same page...I think. Or maybe he also really likes me but doesn't show it just like every other guy has trouble with. Every time I get hit on or a friend/stranger asks me if i have someone, I say yeah. I don't say he is my bf cause thats just creepy without him knowing he is my bf but I just refer to it as, yes I have one interest and I won't stop working for it and I won't be interested in anyone else until I just genuinely get over him and genuinely start liking someone else. I can't force myself to not love him even though he has made me feel very sh*tty. I think of all the factors that tell me walk away from him and yeah it does work but then I close my eyes, I start thinking and my heart just speaks saying, you know you love him and always will despite those bad moments. Sometimes I feel like maybe I am just in love with the guy in my head and thats not who he really is. If thats so, then I'll move on but in spirit I'll be with the guy in my head, who I thought I was with this whole time. I have worked so hard for us to work but it always failed when it was getting better. I would work even harder if he deserved it. If he wasn't so mean, and so careless then I would love to take care of him and be there when he needs me. Seriously, I have put away things just for him. So I can't imagine what I would do if he started acting better. I think at this point though, the only work I can do for us is have hope. I don't think I can throw myself again at him. I will honestly just feel helpless, weak and gross. If I approach him, it'll be more settled because i am aware of his actions and attitude now. All of this makes me think love is limitless, you'll do anything even if its small or not noticeable to stay in touch with that person. I have thought maybe he will by my lost love like others have, but I don't think I can do that unless I just go far far away and take some medication that would make him disappear from my head and heart.
