insecurity

[anonymous]

i am in a great relationship
three years now
very serious
how do i battle the insecurity i have about my significant other
i feel it is a personality trait as opposed to something sparked from i constantly call back trying to get things solved but it often makes things worse
my significant other (although there was this one huge event where i did not hear from my s.o. for a whole week {that is a much longer story} and maybe that huge uncertainty void influenced me for good)
i have little to no feelings that my significant other would cheat on me
but my significant other's friends do some things that raise my eyebrow

if we argue or we're on the fone and i get hung up on i get really upset and call back for a while dependently
and it makes me very steamed off when my s.o. just shuts down when we're having a problem and doesn't talk or try to mend things
we're opposites in this sense because my s.o. says they just need time and i just want to fix things on spot
go figure

i am and have been trying to become much better at being less needy and clingy, but i still some issues obviously

these are just chronic problems that have been in our relationship the whole time
nothing that's going to seriously drive us apart but it needs to be fixed or at least dealt with better than it has been
how do i overcome this insecurity
my feelings and emotions are really at a discomfort if there are problems between us
i wish i was more independent and could still function during fights and worries
but i'm definitely not there yet
