I am in competition with my fiancées smart phone for his attention

Lately (for a while) I have noticed that my fiancée spends most of his time glued to his phone or some other electronic. I have tried to talk to him on numerous occasions only to be met with a fight. I remember when we used to talk and have conversations and now, now I sit there in the chair in our room watching him waiting to see if he will even acknowledge my existence. I sit there for an hour or so maybe two and glance around our room between glancing at him and when I literally get no response from him I start crafting (I am hand making things for my baby because it's cheaper). After about two hours or so of that I look up only to find him still glued to either his phone or some other electronic. I check my phone for the evening deleting spam or junk emails, reply to long distance family or friends if they have written and I check my glow app. After which I get up plug my phone in set my alarm for work the next morning and quietly get into bed without a word, face the wall, grab my body pillow and snuggle into it as I lay awake for another few hours wondering what I could do to possibly make myself more interesting so that maybe we could have a conversation more than a few words long. Or so maybe we could cuddle like old times and be completely focused on one another for more than a few minutes (which is normally when we have sex then it's back to his devices). I can be in the same room with him in the same bed but feel so alone because I pretty much am. I constantly think about what I have done differently that's caused this and 100,000 things run through my mind. I google all kinds of things from how to be a better girlfriend to what can I do to make my husband interested in me again with little to no luck. I have no one I can talk to about anything ever. I've tried countless times to talk to him only to realize he's not even listening to me so I just slowly stop talking and pretend I haven't even said anything. I can literally be right next to him and say something and he not even hear me. Whenever I try to text or call him I'm met with no reply or no answer. When he's home if his phone so much as sends him a notification for Facebook he answers it immediately. I just can't figure out what I had in the beginning that kept him so happy and interested and intrigued that I don't have now. Anyways sorry this is so long and bleh and thanks to those who actually read it. I just needed to get all of this out since I can't talk to anyone around me.
