Your partner is insecure and needy,if your partner is doesn't like you or doesn't need any type of relationship then why hi/shi stey with you, the simple answer is that your partner is fully insecure and maybe needy and you full-filling his/her need. A partner who is insecure has difficulty making a clear choice because he/she thinks "what happens if I like my present partner can I get the next one" and if your partner is needy and want money from you and you give the money then he/she may be always with you but doesn't love you.
