Update-
I was so worried if I should give him something for his birthday which is coming up in a few weeks, or just completely ignore it. However, he brought it up asking "What are we going to do on my birthday?" He followed up with- "Maybe we can go on a date night?" It sounded good to me but didn't show that much enthusiasm.

Yesterday, before ending a phone conversation, he said "I love..." and he cut himself short. Not sure why he didn't continue. He probably wants to say it but when he's really sure (?). I just pretended not to hear and didn't talk about it afterwards.

Praying for everyone.
