expressing feelings

i have been with my daughters father for 7 years. we are pregnant with our second child. we have been having a very hard time lately in our relationship. we have had our share of issues and troubles in our relationship. but i wouldn’t trade this man for anything in this world. i’ve always said since we met we were made for each other. he is my best friend, the love of my life, the light of my life other than our daughter and our child that isn’t born yet. he’s always been insanely insecure but would never in his life admit to it a lot of that causes many issues within our relationship. i’ve never given him a reason to be insecure, that’s just how he has been since we have met. he knows me more than anyone and i know him more than anyone. we have had a bond since the day we met, and i love him more than anything. we are completely irrespirable. however, i can only text my feelings… i have an extremely hard time even saying how i truly feel over the phone, yet alone in person. i have severe anxiety, and i get really nervous and flustered when trying to tell him how i really feel but i want him to know how much i love him i appreciate him and everything he has done for me and our daughter. he is such a strong man, and he works hard for us. i haven’t had to work since i was pregnant with our daughter 4 years ago. he will take the burden and carry us even when he struggles he tries constantly to do as much as he. an for us. he will always choose us over anyone or anything, even family no matter what. the problem i have is i don’t know how to express myself face to face, and i don’t know what to even say for him to truly know how i feel the love and gratitude i have for him. when i try to talk face to face and be serious i can’t, i start laughing, and smiling out of nervousness. or i start and i just try to get away from the topic that i started to begin with. i’ve always been this way. it’s very hard for me. i don’t want him to think im joking about any of this that i want to say. please, anyone help me with this. he deserves so much recognition and praise. what do i say? how do i do this? or do i just give him a gift with a nice little card? or speech? i dont know. i know i sound so silly, honestly. but this is important to me and i need him to know in one of our hardest times how much i still love him and appreciate all he does.
