My (35f) best friend?s (34f) marriage is perfect. Mine is not. It?s hurting both my marriage and my friendship.

My best friend and I both got married last year within 3 months of each other. I?ve been with my husband for 6 years, and she?s been with hers for 5 years.
I love my husband. I really do. But our first year of marriage has been hard. My husband is not very romantic and we?ve struggled to love each other in each other?s languages. But these issues have been amplified because my best friend is in a seemingly ?perfect? relationship and I can?t stop comparing my marriage to hers.
Her husband is constantly doting and is always doing small things for her, like getting her flowers or writing her surprise cards for her to find in the morning by the coffee he made her. He?s always posting pictures of her on Instagram with adorable captions. Yesterday he posted a video he took of her sleeping with the caption ?our love is a movie? and I think they really do feel that way. I know people will say ?you never know what?s going on behind closed doors,? but I do, because she tells me. She tells me how they never fight (literally only once early in their relationship and they resolved it easily), about every small thing he does or says to her every day and how happy it makes her. I literally get about 5 texts or phone calls a week where she just gushes about how happy she is and about how perfect their relationship is. I talked to her about the video her husband posted and she told me it?s true and she often enjoys thinking about how much their relationship looks and feels like a romance film. People may read this and say she?s lying but I?m telling you she isn?t. She isn?t that kind of person.
Recently my friend and her husband came to stay with us for a week and I felt so embarrassed about how much our relationship looked so dry compared to theirs. It made me start to wonder if I married the wrong person, which gives me so much anxiety. I?ve talked to my husband about my fears (although not specifically about wondering if I married the wrong person) and we are trying to work on things. We are seeing a therapist soon.
These feelings are harming my friendship and my marriage, which are the two most important relationships in my life. I?ve started to hope something goes wrong in my friend?s marriage just so I don?t feel so bad about mine in comparison, which is such an ugly feeling. I don?t want to feel this way! Has anyone else dealt with this??? How did you find solace? How did you stop comparing and start appreciating what you have?
My friend sends me new messages about her ?perfect? relationship like every other day now and it?s killing me.
Edited to add: To be clear, my relationship (I think?) is actually pretty normal and while we have struggles, I don?t actually think they?re anything beyond what a normal relationship struggles with. My husband is wonderful and our marriage has so much good about it, and we are great communicators! I think my problem is mostly that I struggle with comparing my relationship to my friend?s, and this makes me doubt my own relationship. Her grass may be greener, but I just want to stop looking at her grass and appreciate my own. I?m not sure how to do that.
TLDR: My friend?s marriage is literally perfect and mine is struggling, and it?s driving me away from both my friend and my husband. How do I stop comparing and start appreciating what I have?
