Asking yourself the tough questions and being completely honest (even if it hurts your ego) is one of the only ways to come to terms that your relationship is abusive in any way. Do you find that you look back to better times with your partner and wish that they were like that today? You might be noticing every aspect of your life being more stressful and less fun.
These are signs that we need to pay attention to because sometimes the little things are what ends up mattering the most. It’s the little things that lead up to bigger things in abusive relationships. If we learn to take note of the small things, then we can avoid the bigger and more harmful things. For example, if you notice your partner stops kissing you when they leave the house, or they are shorter with you in conversations then normal, then those are signs that something is not quite right. Another example is when there is no longer a sharing of responsibilities, and you find that you are pulling way more weight with no thank you from your partner.
When your partner seems to have changed into someone else, and someone else that you do not like, then it takes courage and understanding to leave that situation and enter a life without a negative and possibly abusive person holding you down.
Life is supposed to be fun, and people that see it otherwise should be of no concern to you. Be selfish, and always think of your happiness first.
