All I can say is don't do the 'logical' thing and write out a list of pros and cons to weigh your thoughts. Because you could do this one day, come out with a ton of pros, do it the next day and come out with a ton of cons.

I was in this situation even a few weeks ago. My bf can be very childish sometimes and silly and goofy in situations that don't call for it. Then I started thinking....I wouldn't want to be with a guy who was super serious all the time. So then I'd switch back to being madly in love. Then he would do/say something stupid and I would think "I gotta get out".

I went and got this book called Too Good to Leave, Too Bad to Stay. It's by Mira Kirschenbaum. Basically she takes you through situations that typically kill relationships. Some may seem small but, over time, end up destroying them. If you can make it through the book without having that revelation, then it kind of shows you "I'm making something out of nothing".

It kind of sounds like maybe your just depressed. Depression can throw people for a loop in every aspect of your life. Him asking you those questions could be a sign of insecurity or simply him not knowing your status in the relationship.

Have you ever considered that you may be sabotaging yourself? Sounds like you have a great guy. He treats you nice, doesn't hurt you and maybe just acts goofy sometimes. (All guys act like 12 yr olds sometimes and that's okay).

I have also been guilty of this. Things are just too good and I feel like "this is too good to be true. this can't be a decent relationship" and I sabotage it. I have done this with a few guys. Start accusing them of things and finding little things to complain about when really, I had it pretty darn good. So it is possible that these are your own insecurities surfacing.

I don't have a specific answer for you but hope that you can do a little soul searching to find WHY you are having these doubts. If you truly think it's him and not you, then I'd think about whether it would be better to leave. Good luck in your search.
