I feel unwanted

So my husband and I got married a year and a half ago, he’s military so I had to move from my home town to wear he’s stationed. There was no effort put into a proposal and I bought my own wedding rings. I paid for the security deposit on our house we were renting, I paid for myself to move up here. And he doesn’t tell me anything too personal about himself. He shows little to no love to me, unless he wants to have sex... am I just being paranoid or does it seem like I’ve invited myself to be a part of his life?
