What would you do?!??

I am so confused right now. I have been dating a guy for five months. We went to school together but never really got to know each other. We went out the beginning on 2013 but never hit it off. When he asked me out again in fall of 2013, I really liked him. I will admit he liked me more than I liked him but I still really liked him. He fell for me, hard and fast. In the beginning, he was everything, EVERYTHING I wanted. He made me feel like the only girl in the world. I’ve never had a feeling like that for a boyfriend. Lately, he has been doing things that simply irk me. They are little things but they bother me. I have mentioned these things in previous posts. He recently got a really good job and I feel like he has became so egotistical since. In the beginning, he was so down to earth and now, sometimes, I feel like he thinks he is some sort of god or something. There is a big difference in having self esteem and being egotistical. This is something I have hoped will go away. There are times I wonder if he is “right” for me, but I can’t bring myself to leave because there are some things I LOVE about him. For instance, I can trust him. Never once have I doubted his faithfulness, which is a BIG step for me. I don’t trust easily. He doesn’t mind letting me look through his phone if I want (no other guy has done this, although I don’t ask to look at his phone, he does give me the option.) He misses me when we don’t see each other. He tells me misses me so much. Ive dated guys that when I told them Ive missed them, they’ve said, “youll be alright.” Yeah, Ive dated some winners, I tell ya. He babies me. He pets me and will love on me all the time. He loves being close and doesn’t mind to hold hands, lay his head on me, hold my purse, whatever. These are things I like. I am an affectionate person and I like that he is the same. Basically there are a lot of things I like about him. But deep down, I don’t know that we can ever be each other’s “forever.” There are too many things standing between us. First, most of my family dislikes him to a degree. I am not particularly fond of some of his family. He is more outgoing than me. I think we would have different parenting styles if we were to have children because we were raised differently. We have different views on spending and saving. He is VERY “tight” or money greedy. He likes to spend money on things that people “see” aka his sports car, etc. I like to spend money to have fun with friends and family, and I’m not as money greedy. Money doesn’t make me happy, love does. At times, we have different senses of humor. We don’t see eye to eye 100% on religion, we do on most aspects of religion, but no everything. Im not sure how many of you are Christians, but I do pray about this relationship a lot. I pray that if we are not right or if it’s time to let go, I’ll have the courage to break things off. However, I just haven’t been able to. Ive dated two other guys and when It was time to let go, I knew it and I broke up with them. But this one, I can’t let him go. My biggest fear is leaving and waking up and regretting it, and missing him. I hate that feeling, missing someone. I don’t know if I should keep holding on and see if our love can break through the obstacles, or to just let go. Im just hurt because I love him so much and wanted it to work, but now that the new has worn off, I don’t know if its right anymore. I’m just hesitant about letting go. Anyone been in a similar situation? If you all think I should break up, how do I even tell him? I love you but I want to break up with you? That makes no sense. Stuck between a rock and a hard place here. =( Another thing I have considered is just “taking a break” to see how we do. This way, we could experience life without one another. Maybe I would miss him and we would get back together (of course, I realize me missing him wouldn’t necessarily mean he would miss me), maybe he would miss me and I would enjoy my newfound freedom and single life, maybe we would never speak again? I think a break may be easier than breaking up. Of course, there are so many technicalities to a break (can we date other people? Can we still talk to each other via text/phone or is it completely no contact? Who decides when the break is over?, etc). Someone please help me .Put yourself in my shoes and let me know what you would do.
