This sounds like a tough situation. I'm certainly no expert about your exact situation, so forgive me if I'm off the mark with any of this, but I'll share from my experience and you can take it with a grain of salt.

Long distance relationships are always tough. It makes it extremely hard to feel stable and supported, especially in a new relationship where you're seeking validation and emotional connection. (I'm a Taurus, so I get wanting the stability and depth in relationships.) Try to think up some nice things you can do to share your feelings, such as sending little care packages, or even go old fashioned with letters.

It sounds like it's quite possible that he's just very busy with his job and other activities. It's sometimes a bit exhausting to put lots of effort into a new relationship after expending all of your energy at work, particularly if he's not usually that emotionally expressive, as you said. It doesn't mean he doesn't care, but that he just might need some quiet recuperation time.

However, the other side of that is that you have a right to feel supported and cared for in a relationship. If you feel like your emotional needs are not being met, you absolutely have a right to bring it up with him. Perhaps plan out what you want to say ahead of time so you're not swayed by your emotions in the heat of the moment and accidentally say something you didn't mean or that might start a fight.

Maybe you could agree to have one long "date night" per week where you talk or video chat for an extended period? Then you have something to look forward to all week and you won't feel so neglected if you can't talk with him much the rest of the week.

I know it can be really hard when you fall for someone that deeply. I had an experience where I fell for a guy in the span of two weeks. I know that sounds really quick, but it's the deepest and most intense love I've ever experienced. He sounds similar to your boyfriend in that he worked all the time and didn't usually talk about feelings and was honestly uncomfortable when I expressed any. He dumped me after 3 months, claiming he was too busy at work for a relationship. So, my experience did not end happily. Yours could certainly be better, but you should be realistic about whether you think this is sustainable for you or not. If it's killing you to be in this relationship, it's probably not the right one for you, much as that hurts to hear.

I read somewhere once that love can be like cocaine, and even though coffee is a lot less strong, it's still very stimulating and a lot better for you. I finally found my "coffee" relationship, and even though the feelings of love aren't as overwhelmingly powerful, I feel a lot more secure in the relationship and I still love him a heck of a lot. I wouldn't go back to my cocaine relationship even if I had a chance. (My current boyfriend is a Scorpio by the way, so I totally understand the emotional side of that sign.)

Sorry if that's not what you wanted to hear, but hopefully you can use some of the suggestions to do your best to help the relationship along. Good luck with everything, and give us an update if anything more happens.

My last relationship was not the best, and I carried a lot of with me in my next relationship (currently). I was open and upfront with everything, so he knew why I was like that, how to help, and how not to help - etc.

My advice is... communicate. What's going on through your head? Why do you do the things you do? What do you NOT want in a relationship? What do you want? Explain what happened, and how it affected you. And how they can help, and so forth. Best of luck! ❤️
