Brake or hide that damn phone and watch him freak!! Jk but seriously i hate when people are addicted to their phones.
Early on in my pregnancy (I'm 29 weeks now) I definitely had moments like that with my husband. Not to say he didn't try, but often I felt he didn't try hard enough to understand the emotional hormonal roller coaster that I was on. I felt either depressed or angry 90% of the time.
However now it's a lot better and I chalked a lot of that up to hormones and my body going haywire, so he's much more understanding and caring than he was before.
It's an adjustment for you both even if you have been through it before.
All you can do is tell him how you feel, he may not totally understand but what worked for me was telling him "you don't HAVE to fully understand it, I'm not expecting you too, but I'm hurting and you are kind of hurting my feelings by not taking it seriously, and that makes it worse".
I can relate to you so much. I feel like my boyfriend gets lost in his phone when were together and he acts as though its fine. I have to ask him to spend time with me and half the time he'll tell me in a minute because hes on his phone. Its been really hard and the hormones make it unbarable.
I feel you! My husband has been working full time while finishing up his PhD. He works ALL day then comes home to study. We recently moved to a new state 1600 miles away from my friends and family. The feeling of being lonely stinks. Hang in there! Maybe you guys can schedule a date night :)
