I Feel Neglected By Him

Hello, I am 23 years old and my friend is 30 years old. We live together, we love each other, we have been together for 3 years. I can say that the thrill is still there, but sometimes I feel very neglected, unwanted and repulsed. I may look silly to some of you. I'm just very sensitive, easily hurt and often feel very lonely. I give an example. When we're both at work, he writes to me and tells me that he misses me a lot and that he can't do without me. I'm in a hurry to go home, what am I not doing to go home to him and be together. I long for him, I adore him, I have not cheated on him nor would I. I go home to him and drop everything else. I often have problems at work because I leave suddenly. Porsto is the most important thing for me and I don't care about anything else. He did it too. He left work early because of me. I really appreciate it. However, if we are one day rest together or relax together. He crashes into the phone for hours. He doesn't even talk to me while playing games on the phone. I don't grumble to him, I've never done that. I know how annoying this is for men. I even play the games he plays with him, and I watch football with him, and he's glad I'm interested in his activities. I try never to limit him in anything, I never forbid him anything, I don't have that right either. I don't know why, when I'm somewhere, he seems to miss me, and when I've done my best to go home or rest on the same day with him, he doesn't notice me. He grabs the phone and does not reflect anyone or anything. At first I tried to distract him but it didn't have much effect. And right now I'm supposed to be playing games on my laptop. When we go for coffee somewhere or go out, he is still on the phone for hours without talking. It's pretty weird to sit in the park and play games for two hours instead of talking. I don't want it, I don't want to be trapped on the phone. I also use it often, but I'm not obsessed. I don't want to tell him that I feel this way, he will feel limited. And I don't really want to ask for attention. When he doesn't pay attention to me, I don't do it either, but inside I am very sick. Can I ask you for advice?
