I don't know what to think anymore...was that love? is this not right?

I've had this nagging feeling in the back of my mind...well two, but one I'm willing to admit and write here is that I've been wanting to go back and read this specific post I made on this blog. I remember the post pretty clearly, I believed it was one of the first times I felt I ever felt love...or that i was in love. (The specific post i'm talking about is here ) Currently...I'm in a relationship I thought I wanted. I went back and forth for months about wanting J...whether it was legit feelings or just out of loneliness. I went with legit feelings because...how could I not? I thought there were clear signs. I mean the thought of him wasn't going away after MONTHs, but also there were times where something happened in my day and I wanted to tell him. That was something right? At least I thought. We sorta took our time to get back into the swing of things again...really communicating and talking pretty open and honestly about how we felt and where we were. I was enjoying that and finally felt like, fuck it just go for it. Let's stop wasting time and just give this another shot. Third time's a charm right? And yet now...here I am thinking about...a past love? Or at least the past post about love I made...about someone else. Who, for the most part I can say is basically like my best friend...who happens to be a guy and who I have a long history with...see blogposts from the beginning of this blog till about i dont know a year or two into the blog? Most of the posts were about him. Let's just call him T for argument sake. But anyway, T is definitely one of the few human beings I've ever felt completely knows me and who I never really have to filter myself with. I can and usually am my complete self with him. He almost always knows exactly what to say or what I need to say when I'm in a state of crisis or just in everyday situations. He knows me. I know him. We have a great rapport and just friendship. There are times I tell him things I wouldn't normally tell other people because I know he'll make me feel better or I know I can just say whatever the fuck I want to him and his thoughts about me won't change. The thing is...I find myself wanting to tell him or go to him about certain things than my bf at the moment. My bf of like a week (minus all the said "history"-its complicated, I'm sorry) But there's a certain comfort level with T, a certain way we talk to each other. I don't have that with J and...it's making me worried. I sooo so want to have this level of comfort with J. Perhaps maybe it takes time? I mean J and I were friends since fucking elementary school with a small break from after hs to post college. Which...I would actually categorize as really my formative years. That time period from after hs to college to now, post college, in grad school, I definitely changed a tremendous amount. I'm not the same person I was 10 years ago. or even maybe 5 years ago. I just don't know. I wanted this relationship. Three weeks ago I was all "just fucking go for it" and stop over fucking analyzing or worrying. Just give it a try. You want it. Yet...here I am. I didn't feel any different after we made it "official" or have any sort of revelation or relief that yes, I got what I wanted. I think I was sort of numb and waiting for it to hit me or for me to process it. But...I don't think that has happened yet. What has happened is that I'm constantly now thinking, did i make the right decision? Shouldn't I feel different? Shouldn't I want to hang out with him? Shouldn't I talk to him about this that and the other thing? He should be my best friend right? That's what I wanted. That is what I wanted to work towards but...I just jumped the gun cause I thought it'll happen...or I hoped it would. I guess it's just not happening as fast as I would like? So why am I comparing him to T. Why am I constantly overthinking everything? Why are things still a little awkward? I also don't feel...the fiery passion anymore. Maybe he isn't the one? Or maybe...I'm not who I thought I am. Maybe I'm different... ...there's been a second nagging thought in my head for sometime now...though...unfortunately, I don't think I'm ready to...admit. Or put it out there other than having it in my own head. Where its still sort of safe. Though I guess if anyone is looking really close they'll know... I think.
