Context: When I was 17-20 I was in an emotionally abusive relationship with a total depressed narc who left me with seriously low self esteem, self loathing and anxiety problems. He made me feel like I had no self worth, useless, a hindrance to everyone and nothing great or special about me. It was awful and I luckily escaped after realising I was becoming a horrible person that I didn't recognise with him, my parents hated him and my relationship with them was going sour. I wasn't myself and felt physically ill with stress every day. During this relationship I developed a bad habit of lying to strangers, cab drivers whilst I was out drinking, it sort of became a weird coping mechanism for me to escape my ever so shit life as I felt like I had nothing going for me. I know its weird, but the escape gave me a good feeling. It was never anything serious, just things like where I grew up, things I had done, my job. Nothing about anyone else or serious things. I noticed I would do it when I was feeling particularly anxious or felt like I didn't know where to take the conversation, or if I felt like I seemed boring. (lots of negative self talk back then) I luckily grew out of this habit towards the end of this messed up relationship, and it was also down to maturing I think as well.
I am now with my boyfriend who I have been with for many years, he is wonderful and we have a great relationship. Been there for each other through everything and tough times- things like miscarriage, mental health issues for both of us, but never anything caused by another. He is my rock. My issue is that very early on in our dating period I had that weird urge to lie after a lot of drinks and have exaggerated 2 stories. I told him I had been with my parents on a trip to somewhere that is quite impressive as my dad went with work, (that is actually true) I just didn't go with them. I also word vommed about breaking my wrist when I was a kid, again this is true but for some reason i exaggerated it and said I had surgery. Another dumb drunk impulse comment. I have been so embarrassed and ashamed about it, I have just never confessed that they aren't 100% true. I still suffer massively with anxiety and every time I feel close to telling him about this weird phase in my life, I get a huge fear of him abandoning me thinking I am a freak. I have never done it again since then after the shame I felt, and we have never had any sort of trust issues. I hate myself so much for it but so scared he will think im a weirdo. Any advice how to approach this?
