I texted him last night being nice, I said that I need my space and to leave me alone.
If he can not abide by such a simple request, he has not even begun to grow up, or show you any respect ... let alone the respect you deserve. You sound like you need to just make a clean break of it completely. But, that has to be your decision. What ever you decide, keep in mind, the longer it takes for you to act on your decision, the harder it gets to actually do it.
In his textes he was saying that he will leave alone and if i decide to not give him another chance that i will have to be mean to him in order for him to leave me alone.
Not!
In the voice mail he said he didn't mean what he said in the text messages, that he let his emotions do the talking....
#1 You are not being mean to him, you just want your own life with your own responsibilities ... not his.
#2 Sounds like he is looking for a momma, not a wife.
#3 To admit his emotions were doing the talking is admitting he is not in control of them or himself ... nobody needs that in a relationship.
#4 Do not let him send you on a guilt trip ... that's what little children and self-centered brats try to do ... regardless of the chronological age the person may be at the time.
#5 He is the one that is insecure and he is trying to make you insecure ... don't go there ... you are better than that.
Personally, if it were me, I would tell him I want to break it off because, by his own actions, he has proven to you that he is not what you want in your life at this time ... you will have children to raise later in life, you don't need to practice with him. I would let him know if he continues to contact me, that I will take out a restraining order, if necessary.
Now, that would be my approach ... It worked for me when I had to do it. What course you take, is up to you ... just keep in mind ... mean what you say and be willing to follow through with it, or don't say it at all.
