long term relationships scare me

For the sharing space thing, when the right person comes along your mindset will change, it did for me. I love my space I hate even friends coming to my house but with my past partners you drop the barriers because they mean so much to you, you want them there with you and whenever possible. And also, you wouldn’t see them too regularly if it’s new, but over time as the connection builds, that’s when you’d either choose to be with them in terms of living or decide against it, everything moved at the pace you like and if it’s not what you want, you don’t have to do it. But if they fill your heart with love and care, this is when those fears will disappear and you will want it.
If your wants, needs, desires and opinions etc change, you might change together or you might grow apart. This happens and sadly it’s a part of any relationship. It’s all about taking the risk in hopes for it to work out. But if it doesn’t, there’s always someone else who will align with your values. It always hurts, but in the end it’s truly worth it to find your best suited person.
I, too, hate the idea of long term commitment. But with my last partner especially he meant so much to me I could’ve seen myself being with him a long time. It’s scary allowing yourself to connect with someone that deeply to let them go, but that’s a part of life and the risks we all take. People grow and evolve, even you. You will outgrow some people and connect with others who you never thought you would. And that goes for friends too as we change so much over time and bend our morals, values, ethics and lifestyles which do not always align with our friends.
You just have to enjoy them while they are there and take the risk. Never think too deeply about it until you connect on a deeper level.

I hate the idea of dating. I love the idea of love. I have never been in in love, nor been in a romantic situation like sleeping with someone, holding hands etc. I like the idea of romance but because i've never felt that way abt someone, I also hate the idea of it.
I'm scared of long term stuff. Like if we live together - sharing a bed. I want my own personal space and independence but it seems like you have to give that up in a relationship Why is sharing a bed so normal, I want my personal space. Sure I don't mind spending time with people but sleeping is my time alone and i just dont understand how to adapt with someone always in my business. Another fear of mine is wanting different things. How do people fully trust each other? Sure you could want the same things at the beginning like no kids but then that might change later on down the line and either one of you would have wasted ur time.
I just feel bad because I want to be loved and give love back but all these things scare me and whenever i bring it up, theres always that one person who says I don't deserve love or I shouldn't be in a relationship. But just because you're in a relationship, doesn't mean you give up ur independence, life and personal space. or does it
