If you have not done so already, you might want to seek legal advice with regard to your daughter. If you are required to provide financial support, you certainly need to have this requirement made thru the proper legal channels. You should also be entitled to visitation rights with your daughter.
It is possible that Melissa has met someone who she would like to get to know better. She isn’t at all certain that this is going to work out. So consequently she is playing with your emotions.
It is important that you protect yourself by knowing what your financial obligations are, and that you have a formal shared custody agreement for your daughter in place.
Best wishes to you,
