hi M.. im sorry that you lost your husband so early. im sure it has been hard with your girls being just babies at that time. i cant speak from experiece... b/c im not a single mom. however, my mom was, and my sister and i are 18 months apart, so i feel like i may have something in common with your daughters in that aspect. this is just my personal story... but my mom shared a lot with us. too much in my opinion... about her personal life. she dated a man too, for many years off and on. they argued a lot though. and i remember a lot of it... so i dont think she was very good at hiding anything from us or sheilding us in anyway. well when the time came that they were back together "again" and wanting to get married, my sister and i were probably about that same age as your girls, which is really strange. we had lived with him, moved out, and now we were moving back. so many different homes, schools, and hearing them fight.... it was hard on us, and we werent exactly supportive of him b/c he had hurt her so many times and he just wasnt really an all around good guy looking back. not speaking for you, but i think my mom was just so happy that he finally wanted to marry her, that she went for it, and there for my sister and i had to also. i remember standing at the altar and they say does anyone object to this marriage?? inside i was screaming! but the words couldnt come out. i was so young to have had to feel like this. again, i dont even know what the relationship is like with your guy and your two girls, i am only speaking from personal experience. you have to make your own choice, but listen to your daughters too. they are your life. yes, girls act out and get jealous and needy... but maybe its more then that. make sure they know that you are the parent, and they can talk to you about anything. and i mean anything. my mom told me that too, but also left us with this man, while she had a crisis and went to florida for a month. a man who was already 25 years her senior and was obviously attracted to younger women being that he was involved with her and she young enough to be his daughter. so you can use your imagination to figure out the rest. im sure thats not your situation and i hope and pray that its not for your girls sake. im just giving my personal experience for you to listen to and take what you want from it. i hope that things work out for you and wish you and your girls much happiness.
