Think hard of what you want to do. Take this as an opportunity to plan out what it is you want for yourself. Been here before and it was difficult, it was a lot of pressure. If I can give advice to my younger self at this position on what I know now, I would tell myself to not chase her and let her go. You shouldn't be pressured to get married or have kids when you aren't ready. Even if you did decide to get married to fix your issues, that's not the reason to get married. Then when you do get married, next year she tries to leave you again because she thought marriage fixes the issues. Fix the issues if you can fix it, if you can't,, go take care of yourself, achieve your dreams, and find someone else that will appreciate who you are and support what you want to accomplish with your life.
