In Serious Need of Relationship Advice. HELP!!!?

I've been knowing my boyfriend for approximately nine months now. We were friends for six and have been officially dating for three. Throughout the course of both our friendship and relationship, I have been a combination of happy, confused, and miserable. When we first met, I thought I found someone worth being in a relationship with. He possessed all of the qualities a women seeks for in a man: sweet, caring, compionate, giving, open, and a great communicator. However, he confused me when we first went out on our date (we had been chatting on Facebook and telephone a month prior to going on a first date). When we went out, he was somewhat attentive but was rude; he would hardly look at me when we would talk (only when I wasnt looking), he would walk in front of me, and do other weird things. On the other hand, sometimes he would lightly interact with me. When he dropped me off, he texted me all these messages stating how beautiful he thought I was and that he enjoyed being with me. I didn't get. This wasn't the last time he acted this way. He has done on several occasions when on dates, around mutual friends, or just me being in his presence. He doesn't act like this around other people, whether male or female; just me. I've seen it over and over again. While witnessing this, I was frustrated, confused, and asking myself if he really likes me and wants me to be his girlfriend (which he asked me three times) then why does he act this way. He is extremely giving, and he has showered me with very nice items. He knows that I'm a simple girl and that materialistic things don't really appeal to me. This is one of the reasons he has always wanted me to be his girl. After awhile, and from what I learned about him during our friendship and recent courtship, I've concluded that he feels, and had felt, inadequate around me, which causes him to act the way he does towards me. I'm attractive, intelligent (currently finishing my last semester at a prestigious university), always happy and smiling, friendly, giving, caring, goal-oriented, driven and young. I'm 22 (he's 30) and I have always been told that I'm very wise and knowledgeable for my age. He and even his best friend has stated this several times and commented that I am not like any other woman they've ever met. This is why I'm so frustrated and confused. I have a feeling, and I did after we went out on our first date, that I intimidate him. He plays mind games as well like: intentionally and disrespectfully gawking at other women in front of my face to get my attention, intentionally flirting with my friend (who is the polar opposite of the person I am, although he has some subtle feelings for her), making sarcastic comments, and not really responding when I provide my wise, positive feedback in our conversations. When we first met, we discussed what each of his wanted to pursue careerwise, and I told him that I was pursuing to become an Optometrist and eventually open my own practice one day. Since that day he hasn't really asked anything else or doesn't really inquire. But he brags about me to his family and friends about me when I'm not around (something in which he never told me until recently). Just those little things that he does give me great indication that he feels insecure around me and can't handle someone of my caliber (not to be y). A little background on my BF: he's 30, graduated from a subpar university, lives at home with his mother but has ambition to enter into the sports field with high hopes of becoming a college coach, and currently teaches a substitute teacher at a middle school. All of this has made me miserable. I feel trapped. He is a good man, a good provider, but his intimadation, insecurity, and inadequacy from day one and throughout our whole friendship and relationship are affecting us and most importantly me. I addressed these concerns to him on numerous occasions, and we've argued about this several times. He doesn't agree with how I feel. He thinks I'm making all this up, and that he just doesn't understand. But truth be told, I know deep down inside, he knows he feels that way. He is ruining our relationship unconciously. I want a man he feels he is good enough and deserving of a woman who is independent, goal-oriented, not crazy, smart, loving, and a potential good future wife (all of which he says that I am). He tells me that I am all that a man would want in a woman, especially being that I am always supportive and have given him gifts when none of his exes have ever done that before. I love and care for him, and I know he loves me is in love with (which he tells me daily), but true love wouldn't be rude or be insecure around someone who truly loves you. He has put me into a space where I can't fall deeply in love or fall head over heels because I don't want to be with an insecure man who is going to hurt me. Ple
