Hey there ladybug,
I think the best thing you can do is to take it slow. Maintain whatever it is you do to make yourself happy and fulfilled and do use caution. When your voice tells you something, it may be good to at least acknowledge it (especially before you fall in love and your intuition becomes confused). I personally think that having open and honest conversation about your past is healthy. I usually feel like if someone cheated and they do not feel bad about it, they may do it again. However, some people cheat feel terrible and do not do it again. Of course you can not categorize everyone but I was also cheated on and had a cheating dad and the 2 things that were constant was that they really did not seem to feel very bad about it. I think for some people, they separate sex and love.
The only advice I have about gardening is to keep watering and caring for your own flowers before giving your TLC to another plant 😉
