Many people have posted and offered you advice and support, and I hope you feel their strength and care behind you. Take particular note of those who have advised care if you do decide to end this relationship. Believe the information that is now out there and widely researched: people who abuse animals are far more likely to abuse people, and the longer you are in a relationship like this the harder it is to see how it affects you and changes you. If taking care of Edison helps you to make your decision then use the strength that gives you, Edison is vulnerable and he is dependent on you keeping him safe. Look at Edison's behaviour and how it has changed. Be safe and be strong, what ever you do. I would like to echo the wise words that peaches08 has offered you.I've been there too. I used to wonder how strong women ended up abused...until it happened to me. Some of my friends even laughed, "What?! Uhuh, I can't see him dragging YOU through his house." They have since stopped laughing when the jerk was still stalking me months later. These types of men are very charming, you hung the moon in their eyes...then they start the gaslighting. Then massive fights. Oh, then flowers. Then hitting. Then crying and flowers and they'll never touch liquor again. Then...you get the picture.
