Happy but unhappy

8 years and 7 pets later. Nothings wrong but it also doesn’t feel right. But not together doesn’t feel right either. We aren’t romantic or sexual at all anymore because of her insecurities. I respect it but also I am deprived of touch my. She wants no help working on it and makes little to no improvement. She has no Ssn and is going to court currently to work it out but it may take 6 more years they get it. I do not want to abandon her at all. Also bummed though because she can only work through apps like Uber under my name. We can’t move anywhere because she needs to stay near her mother because she also helps care for her and gets help since it’s technically her mom‘s fault. She is very hard worker though!!! Will work Instacart all day and night every single day and makes sure everything else is always paid for.she pays my bills and helps my rent and is always there for me helps with pets and does anything for anyone because she feels less than because of her situation . she’s wonderful so why do I sometimes feel an urge to wanna go meet new people or even just be single and travel the world. It’s so complicated because she’s absolutely wonderful but there’s also so many issues she does not like to face difficult conversations and will do anything she can to avoid them also afraid that there may be self harm and acting irrational if there is a break up I’m not really sure what I’m asking I just need to vent and get some advice I guess.
