In Need Of Search Angel's Help!!!

:confused: My name is Jessica and I have been searching for my birth mother for 5 years. I have worked with one search angel before and he was unable to find my birth Mother but found a possible match for my birth Father. He got me in contact with the individual and we communicated through mail 3 times. He said he believed he was my birth father. He then stopped writing me after I asked questions about my bm. This was 4 years ago. I have continued searching but have been too scared to contact him because of the circumstances during our last contact. I have recently found some very confusing new information doing my own research, but I am stuck now and need help! Please if you can help me I would greatly appreciate it. Thank you very much Jessica
