<human>: First I want to start by thanking anyone who reads this. It means a lot.

Quick rundown of the relationship:

-Been together 4years

-Each other's first serious relationship

-We both lost our virginity to each other.

-Go to school a few hours away from each other but are from the same area and graduating soon.

I was pretty happy with the relationship but the last 6months have left me feeling very confused. Nothing has happened between us, but I keep swinging between wanting to be in the relationship and not wanting to be in it. Being around her or going to see her doesn't give me any sort of bubbly or happy feeling and sometimes making plans can feel like a hassle. This all sounds bad, but I also know I'm not quite happy with where I'm at in life. 

I'm still working on being happy with who I am. I don't see myself being all that smart, don't have a ton of friends, still finding hobbies, and discovering what career I want to get into. Maybe its depression or maybe it's just being a 21 year old. She understands how I feel about these things, but wants me to try and commit more to the relationship once she moves back. This Is understandable, but I don't know how I can do that just yet. Sometimes I feel I'm just comfortable with her as a person and staying in this because I'm afraid of being alone or that I'll regret letting go later on(this is what has been bothering me the most).

I'm wondering if anyone has gone through something similar or has any advice. Has being unhappy with yourself made you feel uncomfortable with committing? This may sound stupid, but how do you know if you're in love with someone or know that someone is the one? I love who she is, but I haven't felt connected to her in such a long time. I feel comfortable, but I'm not sure if that is love or my fear of letting go and regretting it later on keeping me in.

Sorry for the rambling and if I sound immature. I haven't been sleeping/functioning well this past week. Thank you to anyone who reads!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Been feeling uncertain about long term relationship. Not sure if it's me being unhappy with myself or if I'm just not certain about the relationship.
