My fiance is suddenly love bombing me

I (26 F) have been with my fiance (30 M) for 5 almost 6 years. My view of the relationship has always been a bit rocky due to him lying about trivial things. For example when our daughter was 6 months old, he called me while I was at work and lied about her standing up by herself in the crib when she couldn't even sit up by herself yet let alone pull her self up to stand, or lying to my mother about how a fish jumped out of her fish tank when there was no way for it to jump out (it's a large 125 gallon tank with a heavy wooden lid). The list goes on.

Anyways, other than that, physically we have a healthy relationship, though we're not ones for PDA, even privately all too much. It's probably been 4 years since he's had the revelation that he doesn't like to be touched, like with cuddling and all that. Which is fine for the most part, but I do like to cuddle on occasion which he's never usually in the mood for.

However, the last two weeks he's been very clingy, constantly wanting cuddles and love bombing me with saying how much he loves me, and misses me while he's at work to an unusual extent (he usually is never like this) and all of a sudden wanting to buy me expensive gifts. Last night, he even said he thinks he's emotionally dependent on me when he's never been emotionally needy like this before with me.

My intuition is telling me something is going on, but I'm not sure if I'm overthinking his behavior/actions. What do you guys think? What should I do?
