Sometimes, having a child changes the dynamics in a relationship. We tend to spend more time taking care of the baby, cleaning house, cooking and all the daily things that need to be done. Then we have our partner and then ourselves to look after. It's a lot.
Sometimes we wonder what happened to our relationship, why did it change? Why did my partner change? I believe that what happens is that as a parent, we become so caught up in the daily grind that we forget to look at what made our relationship special.
I read that you see him as a "lovely man and also a good dad". You also mentioned that "I sometimes can't help missing about the time when we first met and I was blindly in love with him". This tells me that you still love him very much but just need time to reconnect. The disagreements that you have can be dealt with when both of you are in a good place.
Here are a few tips to help you out:
1. Plan a weekly date night. It doesn't need to be elaborate or expensive. It could be going for a walk in the park, having a cup of coffee somewhere. As long as it's just the two of you, this will help you to reconnect as you did when you first started going out.
2. Schedule some time to discuss certain issues. When we are upset or angry, we are never at our best to talk about what bothers us. Women tend to be more "emotional" about certain topics and this pushes men to "close down". This gets you nowhere. Make sure that you have a plan as to what you want to talk about. Make it short and precise. Let you partner know that it will take no more than 30- 45 minutes (or whatever time you want but don't make it too long).
3. Plan future activities together. This always spark excitement in a relationship. There is something about planning a future event that excites people. The anticipation of some great time together, to do something different bonds people together. It creates a shared experience.
