How can I stop being insecure in my relationship?

Never swallow part of yourself for somebody's sake... there happiness isn't defined by you being a certain type of way. There the bigot while you get to smile at them and say I am who I am. It's a matter of accepting yourself... if they have an issue, its there issue not yours. Hence Being offended is fucking bullshit and further more makes respect a void concept.

The most important thing in a relationship is loving yourself and being self-confident, only that way a relationship works ;) And communication too! When both talk about what are they feeling and try to help each other, everything is beautiful

By embracing the fact that NOTHING is for FOREVER. Accept that people will change. Accept that being insecure means that you love the person.

A relationship is a big step, I think that by being in a relationship you already faced and overcame many insecurities with yourself even if you didn't realize, soif you are already in a relationship you are not just dealing with your emotionsa and the best for your security and wellness in all states but also of other person, so there's a bond between you, in which you shouldn't feel insecure about, you should probably just remember the reason why you and that person got together and realize of all the things that bring you together instead of the ones that tear you apart and if after placing the goods and the bads of the relation is very important to keep connection with your partner and tell them how you feel and all of your problems they probably will understand or at least try because they obviously care for your wellness and if they don't you shouldn't stay with that person, you can always work on your relation, make the bond stronger but if you realize that the relation is not making any good or is making you suffer in any way you just end it, and focus on yourself. (not that abrupt though, always try to understand your partner too)

that stage will come with time. if you can't right now? then you can't right now. trust me, you are not mature enough. i am just being freaking honest here.

Try to stay within your bounds and comfort levels. Don't do anything your partner suggests or wants unless you either want to are comfortable doing so. It's also not bad to ask them to affirm you

He/She should make you feel beautiful both on the insides and out.

Well, you first gotta be sure that your partner is there for you, that he can understand and support you. Talk to your half about these things, don't keep them inside. After you cleared that out, it's as easy as that trust game, when you let yourself fall and you get caught by your partner. If it's a strong, healthy relationship, you'll see how easy it gets to feel confortable with the loved one. I hope this was helpful, and i also hope you'll succeed.

By believing in yourself and trusting that you're more than enough you don't need anybody but yourself to be happy

Insecurity is just a construct you created for yourself, and the moment you realize that your relationship isn't fully dependent on your seen good qualities, you will stop being insecure. Your lover won't see the imperfections you do, whether its the way your laugh sounds or the way your nose crinkles. Chances are, your significant other even finds your insecurities adorable since they're a part of you.
