When in doubt, leave these type of guys alone. When we feel this conflicted about a guy it`s our intuition as women struggling to keep us safe. I`ve been in your situation many times as a young lady with low self esteem in my early 20s and as a 30 year old I look back and think how did I put up with that? I`m still fighting low self esteem even at this age but it`s never worth accepting less from a guy because we want attention. Trust me on this one. Good luck.
