what 2 do

I've been going wit this boy for 5 months now and everything was o.k. but in the last days i feel like we are like kinda losing a connection. I've tried talking to him about it but he says that theres nothing wrong. Then I still have this feeling that somethings missing but my last realtionship this same thing happen and I dumped the person I was going with and after I did this I regretted it deeeply. So I don't want to make the same mistake like I did in my last realtionship. I also get moody alot so one minute I like him the next minute I'm not so sure so what should I really do.I know he loves me because his sister tells me that he treats me better than any girl he's ever been ouot with and I don't want to make a mistake that I might not be able to fix.

I'm Not Sure If Anything Is Trully Wrong With Him...Maybe The Relationship Isn't As Exciting As It Once Was, And Then Again Maybe Its Your Mood Swings Giving You Mixed Emotions And The Wrong Feelings About The Way The Relationship Really Is, Before You Say Somethings Wrong With Him Check Yourself First...And Try To Make This Relationship Work...5 Months Isn't Worth Throwing In The Towel Over a Silly Situation Such As "Unsurity".....*Good Luck And I Didn't Mean a Thing I Said Harshly...Just My Opinion* xoxo-Nikki-xoxo

theres nothing wrong it's all pyschologicial (spelt right?) it's all in your head if somethiong was wrong with the relationship and he loves you (like you told) then he'd admit that something was off.
