After dating this man on and off for 6 years, I found out he has been in another relationship for the last 4. We talked about getting married and engaged by the end of the year and meanwhile he was still dating several other people. After finding out he was in another relationship for 4 years, he said he really wanted me and promised he had told me everything. recently, I received a “letter” from another ex-girlfriend saying that he was involved with several other people. Who knows the whole truth, but he was definitely involved and dating 3 other people during the last 4 years. Ladies, this man is a problem and has severe issues. Stay away from him if you ever want long term happiness.
