Alright here's my analysis of the game so it's hopefully easier for others.
The game feels like RNG for the most part, like a dice roll, you have a chance of getting a low roll or high roll but pairing certain actions can increase the chance of a high roll per se.
My experience is a bit rough but after getting into it and learning of the system (again, man I felt rusty), I found a solution.
-Diversity on your moves are important, especially in the latter half as they will become ineffective. Act Act, Talk Tak and Talk Act/Act Talk are recommended for learning how to win. Also take advantage of momentum but don't assume you've won until you are able to pick escape.
- Take advantage of Reason, the game allows you three lives somewhat. In battle after moving to zero in HP, you will be revived like in Lust Friend, giving you a second wind. You start with 50 health however and 30 on life three. As such try to setup quickly before she starts to double attack like on day 3.
-Struggle and Fight Back must be used in moderation, as opposed to using Resist or Accept, these two actions will cause her to deal 30 damage as opposed to 5 or 10 as a counterattack. Wait for an opportunity and provoke tends to make sure you don't get ruined.
-Take advantage of Temptation events, when fighting to escape there is a chance Cowgirl will try to tempt you, this is good as picking resist will make it your turn again, use this as a point of counterattack.
Edit: little note before I go, don't be afraid to save scum. The game can be unfair sometimes especially the fourth day.

I hope this helped a bit, the game wasn't hard but it definitely gave me some pause from time to time. As such just have fun and if you find yourself struggling I'm willing to help.
May we meet again on another thread, and wish you luck on battling that pesky bovine. Also take care fellow internet stranger.
Till Next Time.
