First time posting on this topic (name changed for the occasion), but I am a proper lurker and have found comfort many times on the step-parenting threads. At the moment my relationship all feels like it's coming unglued and I'm here to ask for your insight and suggestions of how you may have handled a similar situation.
Have been with DP for 2 years, live together and share custody of DSS (8) with his ExW. It's meant to be a 50/50 arrangement, but we often end up having DSS about 60-70% of the time. That part is all good and well - have a fantastic relationship with DSS, and despite some irritation about juggling schedules to cater for ExW's ever-changing plans, it's all fairly straight forward. Likewise, DP is wonderful - this is the man I want to spend the rest of my life with. Fortunately he is extremely supportive and generous concerning my feelings about the dynamics of step-parenting. In fact, he is so supportive that I fear I have allowed some of my personal issues (primarily my ridiculous resentment towards ExW) to take up too much space in our relationship. I label it ridiculous because I know it is unreasonable. Outwardly things look fine - we adults have very pleasant interactions and I know (from what she's said to DP and mutual friends) that she is incredibly grateful for my parenting contributions. The thing is, I just don't like her. I don't like how she behaves or how she treats/has treated DP & DSS. And I certainly don't like the negative impact she has on me and my mental/emotional well-being - I've come to violently resent her position in my life. But, perhaps most importantly, I truly dislike the fact that I even harbour these negative feelings.
I can't change the past - and I know I can't change the things she's done (& continues to do) that impact my life in negative ways, but surely I can turn some of my negativity towards her around? Because at the moment I'm taking my anger out at DP and it's beginning to destroy what is a really good, loving relationship.
So, ladies, I beseech you - please share any wisdom and insight you might have. How have you helped yourself feel more positive in dealing with your strong negative emotions concerning the ExW?
