Long distance marriage

Am new to this group but i feel like am the grandmother of long distance.

Background: my husband and i went to the same primary school, ended up meeting online at campus and went into a distance relationship. After 3 years we married. I live in europe, he is africa. For his phd he went to USA for 3 years. but for part of the research back to Africa. He travelled a lot between all continents before the pandemic and we endeavour to meet on those work trips in europe, went to USA, He came to europe. And 5years into our marriage we had our first. We had put off kids because we wanted to solve LSR first. Our son is 2 now, i really want another child but we cant ttc because of LDR, further more am beginning to feel like 7 years (7 in marriage, 3 in relationship, total 10) is a lot to do LDR, We have struggles but cant seek out counselling because no one seems to respect we are in LDR because we have to finish school. They cant even counsel and address our problems without saying it is due to long distance. And now am also beginning to feel the same. When i tell him i miss the affection, he tells me to wwit until LDR is done. It has become a go to, to avoid solving anything in our relationship. Honestly am tried. I dont see an end to this because he seems comfortable where he is and am not ready to move to Africa. I have really thought of a separation this past year but i do second guess my attitude too because am well aware it takes 2 to tangle. But also when i tell him what i dont like, he points fingers at me to say u think u r perfect? So nothing gets dealt with. When i say nothing, he doesnt tell me what i need to work on so am lost of what to do. Am Honestly tired.

I always believed divorce only due to cheating and i have no proof he has cheated. Neither have i. But i don't feel like we are in love anymore. We do love eachother but more like platonic and do a lot together and share information about a lot of things probably more than many couples i see living together. He is busier and is trying to finish his PhD but at the cost of our relationship. When i suggest we meet up, he says i dont take his work seriously. But i feel he doesnt treasure his family enough. I would travel but i have a baby and in this pandemic, really it is easier for him to move especially given he can work from home. I already flew over with our son a month ago and we narrowly escaped out due to the pandemic hitting hard while we were there.

I really wish he could be more emotionally present and i already struggle alone with our son.

I think you can read out of my post that i cant put a finger on what exactly is wrong.

Didnt want to post in the marriage support group because they wouldnt understand long distance like you guys. Hope i can get a few tips.
