I feel alone

My boyfriend recently lost someone about three weeks ago and he’s been really distant. In which I can understand, but I can’t help but feel alone. For the past three weeks, we haven’t seen each other. Today was the first time we talked on the phone. We’ll text maybe 4 or 5 messages and then he’ll stop responding to me. I told him how I felt and he said I was being selfish. But, when I look on Instagram or Facebook, he’s active damn near 24/7. I’m trying to be here and comfort him and he’s not even talking to me, so it’s like who are you finding comfort in and why are you pushing me to the outside?

How do you keep your personal feelings of neglect aside to be supportive of your spouse? Ig it’s weird for me because I’m and only child and I like attention. And in my mind, I’m thinking, you love me and care about me, but you can go three weeks without answering my calls or calling me back and half texting me? You say I keep you grounded, but when you’re going through a hard time, you act like you don’t want me around and can go days without talking to me...
