Need a person to vent too!!!

I feel so alone, I cry myself to sleep at night most nights.. I'm sick of crying all the time. And faking that everything is okay when it's not. My boyfriend and I have been together for awhile. It will be a year in June. My longest relationship since my first boyfriend when I was 14. He was such a sweetheart before we got together and now that we're together everything has changed. He used to give me body rubs, we used to have sex a lot, I mean our sex life is still great when it happens, he used to eat me out all the time, we used to spend a lot of time together when we first got together we were inseparable. Well lately it's changed and it's breaking my heart because I love this man with all of my heart, not like anyone else. He gets annoyed when I try to kiss him more than 3 times, he swats my hand away when I try to play with his penis. He doesn't rub me anymore, and if he's not at work he's playing video games, and I don't wanna be stuck there watching him play cause it's boring. I feel like he's growing away from me and I honestly can't take how I'm feeling and whenever I try and talk to him, he asks are you trying to start an arguement. I'm broken... I wish he would cuddle me like he used too, rub me like he used, and wanna spend time with me like he used too. I feel like unless he's horny or in the mood we don't have sex. I try to get him in the mood and he pushes me away, and it makes me feel very unwanted and I cry myself to sleep cause it makes me think am I too ugly??? Why won't he let me touch him? I know for a fact he's not cheating. Unless he's talking to a new girl at work that I don't know about and only talked to her at work. We've talked about marriage and kids and we want to have a baby. But I'm just so confused on why he's not so touchy and lovey like he used to be!! Why me?!??? I just want my man back! 😭😭😭😭😭😭😢😢😢😢😢😢 Like when we have sex there's no foreplay anymore the only thing he wants is me to suck his cock. And he gets off super fast. I have no time to get off myself. He don't finger me anymore, he doesn't eat me out, so it makes me feel like there's something wrong with my vagina like it stinks or something but it doesn't. I'm so lost! I can't lose this man he's my world, my rock, my soul, my heart, HES MY EVERYTHING! I just don't understand what's changed... 😢😢😢😢😢😭😭😭😭

Here's a poem I wrote him too:

To the love of my life,

Almost a year ago you walked into my life and I haven't been the same since. You are the love that came without warning. You had my heart before I could say no. I originally wasn't looking for a relationship, but you came and swept me off my feet. No matter how hard I tried to push you away, you always came back. I don't know why you did because I'm a pain in the ass, but I'm glad because if you didn't I wouldn't have found my confidant, best friend, the love of my life. 

You're here for me through everything. Whenever I have a bad day you're the first person I turn to because nothing is more comforting than being wrapped in your embrace and listening to you tell me everything is going to be okay. Sometimes when I'm being irrational (which is actually a lot) you tell me and I always protest, but you're always right. You don't even have to say much, but just knowing that you're here by my side through everything is enough. You make me a better person. I hate the phrase "better half" in a relationship because I believe that people in a relationship should be their own person, but you help me be the best possible version of myself. You are always on the sidelines cheering me on, no matter what crazy project I decide to take on next. Watching you succeed makes my heart happy. Nothing inspires me more than my love succeeding and conquering his goals. You're my rock. You inspire me immensely. You have a huge heart and would help anybody if you could. You're the most genuine person I have ever met and tell people exactly how you feel about them. You don't sugar coat anything and that's a blessing in disguise for me. You're smart, driven and passionate. That's everything I was looking for and more. Of course we fight, but what relationship doesn't have bickering moments? They say love is blind, but it's not. Love is all-seeing and accepting. Even though we both have flaws and irritate each other constantly, at the end of the day we accept each other for who we are. Love is seeing all the flaws and blemishes and accepting them. Love is recognizing all the fears and insecurities, and knowing your job is to comfort. Love is working through the painful times because you know your significant other is worth it. Infatuation is fragile and will shatter when life gets rough. Love is strong and it strengthens because it is real. Let me tell you, you're worth it completely.  I can't wait until we have our own house 10 years from now and we can nit-pick eachother all the time while cooking dinner and watching reruns of The Walking Dead. Nothing excites me more than going through all of the stages of life with the love of my life by my side. I love you for all that you are, all that you have been, and all you're yet to be.
