Acting strange

I feel kinda bad posting this, but I feel my husband has been more detached lately. I know everyone argues n has relationship problems but I feel like this is different.

I don't think he's cheating on me or anything, but I've caught him in several lies lately. he's also alot less clingy, talkative, and motivated.. we are both really stressed out because of finances, but that doesnt make an excuse for these things.

It worries me because we are expecting our first child and married for 2 years.. I don't want things to get out of hand. I love him and don't ever lie to him, I tell him everything.. it just doesn't make sense. Am I just being to hard on him?

Thanks for listening
