I have been in a not so great relationship for the last 2 and a half years.. In that time, we had our daughter who is nearly 2 years old. At the start of the relationship, he was telling me how he's a great father (another daughter from a previous relationship), how he is hands on, how is faithful, respectful, loving, caring... I was sucked in hook, line and sinker.. Went I found out I was pregnant, he told me he had cheating on me with his ex, that felt like a dagger in the heart.. Of course, he was all so apologetic and in time, I forgave him as I was expecting my first child with him. As time went on, he turned into jekyll and Hyde.. very aggressive towards me, in my face, even when I was heavily pregnant.. it was scary at times but then he would be all apologetic again.. as time went on, it was getting more and more often, but this time, instead of blaming me, would make me believe it was my fault.. I had our daughter, but he didn't keep to his words of being a doting dad.. I did EVERYTHING.. and still do.. He has become more and more manipulative and I began just to except this and take the blame.. it was easier..and I didn't want my child to see his temper..It happened again on Christmas Day, shoving me, dragging me, throwing my phone out of the window but yet again, I apologies and took the blame to save what christmas we had left.. All the time, in know what was happening and what he was doing, but I kept biting my tongue... We have recently split up, I couldn't take it anymore.. but now I'm just feeling resentful and very emotional.. He is doing what ever he wants to do.. going out.. meeting/chatting to girls.. whilst I'm at home feeling a failure and feeling like a total utter worthless human being.. I'm crying all the time and its not good for either me or my daughter.. and I hate feeling this way.. I can't stop him from seeing his daughter as much as I would love to as I'm her sole carer.. I get a little of bit of maintenance a month but not by any means that helps towards her upkeep.. I'm paying for everything.. doing all the hardworking, looking after our home, bringing up my beautiful daughter and going to work, whilst he has the life of a singleton, doing what ever he wants.. having a life!! I just feel sick all the time.. I wish I could just disappear for a month, let all the emotions go and then come back, but I can't... I'm really struggling to move on.. Any advice I would greatly appreciate..
