How to be better...

I know this is probably not the place to post it but I’m struggling... I am trying so hard I’m just a big over thinker but lately I never feel like I’m good enough for my boyfriend even tho he always says I am.. but his friends who I thought liked me have turned and told me they don’t think I treat my partner right.. it’s one of those things I know they are probably just saying because I asked my partner and he said he’s happy and he knows i am always wanting to make him happy.. we are trying to plan to get pregnant and start a family but this is always on my mind I constantly think of what his “friends” said to me.. how do I get past this? I feel like I annoy my partner constantly because I’m such a wreck.
