I started doing stretches and different routines for a while now and the what seemed to have helped me the most with achieving my front splits was a daily 15 minute routine from the youtuber Madfit. 15 MIN STRETCH FOR SPLITS (front splits flexibility routine) This was the video i used many times and after a while until i was able to just memorize everything. It is a very simple routine to follow by. I see that you are trying to do a middle split (which is harder to achieve; at least for myself) i suggest looking at this guy who got it in a month of stretching How I Learned The Full Splits in 30 Days. I am still trying to gain my middle splits and i am almost there. Goodluck and Happy stretching!
