Our bedtime routine sucks

Our baby is 7mo (soon to be 8mo, at the end of the month). Our bedtime 'routine' just sucks. She is tired around 7 pm, I try to put her to sleep (I am breastfeeding her to sleep), she maybe takes a nap of 15-30 minutes and then she is ready for more wake time. And this goes on till almost midnight! This is not a new thing, it is happening for months, and I thought it would pass, but I am exhausted. Most days she doesn't even nap during the day, or her naps are very short. My husband is working all day, so I am alone with her, and since we live abroad, we do not have any help. Did someone have a similar situation?
