Feeling burned out and uncertain about the future of my relationship. What advice would you give? (F26/M35)

Hi Reddit, I'm feeling a bit stuck in my relationship, and it's weighing heavily on me at times. I really love my partner, and I know he loves me too. We share a wonderfully romantic life together, and it's not often I feel this way—it's like we're soul mates in many aspects, sharing similar views, values, and tastes. However, every relationship has its challenges, and ours is no exception. Lately, these issues have become increasingly overwhelming, making it difficult for me to cope. To summarize, our physical relationship is lacking. We hardly have sex, and it’s taking a toll on my self-esteem. I find myself imagining him with other girls just to feel okay during moments of intimacy with myself, which isn’t what I want. I often long for him to initiate sex, but when that doesn't happen, I’ve caught myself justifying it in unhealthy ways. While journaling, I’ve become more aware of my feelings. Recently, he's started creating adult content for other women, something I’m not comfortable with at all. When I share my feelings, he gets upset and accuses me of hindering his ability to make a living. He wants my help with promoting it, but I just feel jealousy and resentment, so I hesitate to get involved because I don't want negativity to affect his work. He claims it’s hard for him to be intimate with me because of how protective he feels. He’s promised to address this, but I haven’t seen any real change, and in the meantime, he spends his free time watching other women. This topic is a sensitive one for us. We’ve tried to talk it out during drunken discussions, which ended in a breakup for a day and a lot of tension. When sober, he reassures me that he’ll make an effort to improve our sex life. I recently told him that I would have to consider ending the relationship if things don’t change, despite my deep feelings for him. He seemed hurt by this and reiterated his willingness to work on it, but a month has gone by with little progress, and I feel myself slipping back into a depression. Another issue is my desire for more independence. He tends to be very protective when I want to go out alone, believing that I’m vulnerable and at risk. I'm unsure how to approach this situation. I don’t have many friends to confide in, and my family is distant, so I’m reaching out to a broader audience in hopes of finding someone who has been through something similar. How did you navigate these challenges? Sorry if this sounds a bit like a rant; I'm just trying to share my perspective! Thank you!
