Relationship going through a dry spell?

My boyfriend and I have been together for almost a year and a half. We’re in our early twenties and live with our parents while we save up money to move out. Buying houses where we live is really expensive.

We’ve had our ups and downs but we’ve worked through it all. He’s told me he wants to move out with me and we’re planning to move in another year.

Recently we came back from a short trip which was amazing. We had an amazing time together.

Since then there’s been a bit of a dry spell. It’s like we’re both talking to walls. I bought it up today and he agreed that we haven’t had much to talk about recently.

He’s busy with studying for a qualification and work and I’ve been trying to keep myself busy too but I can’t shake the feeling that we’ll drift apart. Especially since our conversations have been going around in circles.
